(x+y)3=x3+y3+3xy(x+y)
(x+y)3=x3+y3+3xy(x+y)-(X – Y) 3 = X 3 – Y 3 – 3XY(X – Y) Or (X – Y) 3 = X 3 – Y 3 – 3X 2 Y 3XY 2 Was this answer helpful?It is clear that when $x=y$ we have $x^3y^3=0$ Then use long division to divide $x^3y^3$ by $xy$ and the result will be the equation on the right Another way would be to write $$\left(\frac{x}{y}\right)^3 1$$ Now we wish to find the zeros of this polynomial
So we set it = 0 i*sqrt(3)(x1) = 0 x1 = 0 x = 1 Then substituting that y = y = y = y = 1 So we end up with all solutions {(x,y) x y = 1} plus the one solution (x,y) = (1,1) Now if you were asking about xy instead of xy, the answer would be xy is always either 1 or 2 Are you sure you didn't make a typo and you were asking about xy and not xy?यदि x 2 – 9x 1 = 0 है, तो x 3 1/x 3 का मान क्या है?Mathx=\sqrt {3\sqrt 5}=\sqrt {\dfrac {6–2\sqrt 5}2

4 It's two equations, with two variables We can do what we always do You can write y = 8 / x, and substitute into the first equation, obtaining x3 / x3 = 72 From here, we want to write this as a polynomial, so we multiply through x3 so there are no negative powers, and then move everything to the leftThe algebraic identities for class 9 consist of identities of all the algebraic formulas and expressions You must have learned algebra formulas for class 9, which are mathematical rule expressed in symbols but the algebraic identities represent that the equation is true for all the values of the variables For example;Because according to ncert its answer is (polynomial example 23(ii)) if it is wrong then why and where plz me

1 How do you simplify the cube of a binomial?(xy) 3 = x 3 y 3 3xy(x y) x 2 y 2 = (x y)(x y) x2 = 1/x 2, 24 = 1/16 = 1/2 4 (x a)(x b) = x ab;X^3 y^3 = (x y)(x^2 xy y^2) (identity) (2i) = (2i)(x^2 xy y^2) Divide both sides by 2i x^2 xy y^2 = 1 Add 3xy to both sides x^2 2xy y^2 = 3xy 1 (x y)^2 = 3xy 1 (2i)^2 = 3xy 1 4 = 3xy 1 3xy = 3 xy = 1 y = 1/x, x
Solution (By Examveda Team) Given, xy = 2 cubing both sides (xy) 3 = 2 3 => x 3 y 3 3xy ( xy) = 8 => x 3 y 3 3×15×2= 8 => x 3 y 3 90 = 8 => x 3 y 3 = 02y=2 y=1 Hence, putting the value of y again in any of the above three equations will give the value of x So, taking equation x=y5 x=1–5 x=4 So the final answers are x=4 and y=1 For any clarification, please update in comments And if you liked the answer do upvote and sorry for any grammatical mistakesThere are two variables and one equation so there will be an infinite number of solutions Let's solve for y xy = xy x = xy y factor out the y x = y (x1) x x − 1 = y so y = x x − 1 x ≠ 1

(i) (99) 3 (ii) (102) 3 (iii) (998) 3 Solution We will use the following algebraic Identities to evaluate the given expressions (x y) 3 = x 3 y 3 3xy(x y) (x y) 3 = x 3 y 3 3xy(x y) (i) (99) 3 = (100 1) 3 Identity Here we can use (x y) 3 = x 3 y 3 3xy(x y) Let us substitute x = 100, y = 1 (99) 3 = (100) 3 (1) 3 3(100)(1)(100 1)Solve your math problems using our free math solver with stepbystep solutions Our math solver supports basic math, prealgebra, algebra, trigonometry, calculus and more1 Which of the following expressions are polynomials in one variable and which are not?
We know that ( x y ) 3 = x 3 y 3 3xy ( x y ) Now subtracting 3xy ( x y ) on both sides we get ( x y ) 3 3xy ( x y ) = x 3 y 3 3xy ( x y ) 3xyNear (x, y)=(3245, 197), (309, 845), (25, 9) and (2365, 15) And since the two equations can be combined into a quartic in x, (or a quartic in y) and a quartic has 4 roots in the complex numbers and we have found 4 real roots then these are the only solutions even if you allowed x and y to be complex numbers Here, exponent of every variable is a whole number, but x 10 y 3 t 50 is a polynomial in x, y and t, ie, in three variables So, it is not a polynomial in one variable Ex 21 Class 9 Maths Question 2
• (x y z) 2 = x 2 y 2 z 2 2xy 2yz 2zx • (x y) 3 = x 3 y 3 3xy(x y) • (x – y) 3 = x 3 – y 3 – 3xy(x – y) • x 3 y 3 z 3 – 3xyz = (x y z)(x 2 y 2 z 2 – xy – yz – zx) Also, check the NCERT Solutions for Class 9 Maths Chapter 2 from the following link Also Check NCERT Books for Class 9Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals For math, science, nutrition, historyIf x 2 – 9x 1 = 0, then what is the value of x 3 1/x 3?
(x y)^3 = (x^3) (y^3) 3xy(x y) so, (3)^3 = 9 3xy(3) so, 27 = 9 9xy so, (27 9)/9 = xy so, xy = 18/9 = 2
