Multiply
3x + 3
by
4x2 + 4x – 2 (Points : 20)

math 
Jai,
(3x + 3)(4x^2 + 4x  2)
12x^3 + 12x^2  6x  12x^2 + 12x  6
note that the 12x^2 and 12x^2 will cancel out, and we combine 6x and 12x:
12x^3 + 6x  6
hope this helps~ :)

math 
Mgraph,
(3x+3)(4x^2+4x2)=
3x(4x^2)+3(4x^2)+3x(4x)+3(4x)+3x(2)+
+3(2)=
