Question

(4x2 + 2y) (3x + y2)

Answer 1

To make it easier on yourself to see the workings, split the first bracket into two.

4x^2 (3x + y^2) + 2y (3x + y^2)

= 12x^3 + 4x^2y^2 + 6xy + 2y^3

Answer 2

I Think ur question is (4x^2+2y)*(3x+y^2)
Then we know that (a+b)*(c+d) gives ac+ad+bc+bd
\[4x ^{2}*3x+4x ^{2}*y ^{2}+2y*3x+2y*y ^{2} \] combine like terms to simply
