Question

factorize the expression 8x³-125y³+2x-5y​

Answer 1

Solution:

____________________

We know the algebraic identity:

a³-b³ = (a-b)(a²+ab+b²)

______________________

Now,

8x³-125y³+2x-5y

= (2x)³-(5y)³+2x-5y

= (2x-5y)[(2x)²+(2x)(5y)+(5y)²]+(2x-5y)

= (2x-5y)(4x²+10xy+25y²)+(2x-5y)

= (2x-5y)[4x²+10xy+25y²+1]
