(x^2 2)(x^3  4x + 9)
(x^2) (x^3) = x^5
(x^2) (4x) = 4x^3
(x^2) (9) = 9x^2
(2) (x^3) = 2x^3
(2) (4x) = 8x
(2) (9) = 18
Now, we add the righthand sides of the equeal sign.
x^5  4x^3  2x^3 + 9x^2 + 8x  18
x^5  6x^3 + 9x^2 + 8x  18
There I did the 1st one for u. Try and do the rest.

(2x4y)(2x+4y)
4x^2 + 8xy  8xy  16y^2
4x^2  16y2

(8x3y)^2
(8x  3y) (8x  3y)
Try finish it from there...
