Question

use identities to find (2x^3 +3y) (2x^3 + 5y)​

Answer 1

Answer:

(2x3+3y)(2x3+5y)

=(2x3+3y)(2x3+5y)

=(2x3)(2x3)+(2x3)(5y)+(3y)(2x3)+(3y)(5y)

=4x6+10x3y+6x3y+15y2

=4x^6+16x^3y+15y^2

Answer 2

HERE'S YOUR ANSWER BUDDY,

using identity, (x+a)(x+b)=(x^2)+(a+b)x+(ab)

therefore,

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

=4x^2+6xy+10xy+15y^2

=4x^2+16xy+15y^2

So that was the final answer...
