Question

Find the product of (x^2 + 2x −3)(4x^2 − 5x + 6).

4x^4 + 13x^3 − 16x^2 + 27x − 18

4x^4 + 3x^3 − 28x^2 + 27x − 18

4x^4 + 3x^3 − 16x^2 + 3x − 18

4x^4 + 3x^3 − 16x^2 + 27x − 18

Answer 1

Last one.

Answer 2

Distribute it then sum similar terms.
(a+b+c)(d+e+f)=a(d+e+f)+b(d+e+f)+c(d+e+f)

Answer 3

It's better to do it yourself than simply copy the solution.
