Question

s) verity x3 + y3=(x+y) (x2=xy+y2)​

Answer 1

it's right or wrong................

Answer 2

x³ + y³ = (x+y) (x² - xy + y²)

we have to prove LHS = RHS

$\mathfrak\red{In\:RHS\:part}$

• (x+y) (x² - xy + y²)
• x(x² - xy + y²) + y(x² - xy + y²)
• x³ - x²y + xy² + x²y - xy² + y³
• x³ + y³

LHS = RHS
