Answer:
4x^412x^3+16x^2
Stepbystep explanation:
(4x+4)(x^3+4x^2)
a b c d
using foil method multiply
term a by term c and d
4x * x^3= 4x^4
4x * 4x^2= 16x^3
*dont forget to add the exponents, when x is by itself you it always has an imaginary 1
then multiply term b by term c and d
4 * x^3= 4x^3
4 * 4x^2= 16x^2
line up all of your answers from biggest exponent to smallest
4x^416x^3+4x^3+16x^2
we can combine like terms with 16x^3 and 4x^3 becaus ethey have the same exponent value
4x^412x^3+16x^2
