Question

Multiply.
(x^2+ x - 2) by (x^2- 2)

a. x^4 + x^3 - 4x^2 - 2x + 4

b. x^4 + 3x^3 - x^2 + 2x + 4

c. x^4 - 3x^2 + x -4

d. x^4 + x^3 + 4x^2 + 3x + 4

Answer 1

Foil this out just as you would any other set of factors.

Answer 2

foil first to get \[x ^{4}+x^{3}-2x ^{2}-2x ^{2}-2x+4\] then simplify to get \[x ^{4}+x ^{3}-4x ^{2}-2x+4\] or A
