Question

(2x-5y)³ (2x+5y)³ simplify​

Answer 1

Step-by-step explanation:

(2x-5y)^3 {(a-b)^3}

(2x)^3-(5x)^3-3(2x)(5y)(2x-5y)

8x^3-125y^3-30xy(2x-5y)

8x^3-125y^3-60x^2+150xy

(2x+5y)^3{(a+b)^3}

(2x)^3+(5y)^3+3(2x)(5y)(2x+5y)

8x^3+125y^3+60x^2y+150xy^2

multiply both eqn

we get..

16x^3+300xy^2
