Question

Multiply (x − 4)(x2 + 6x − 5)

Answer 1

`x^3+2x^2-29x+20`

Explanation:

We use the Foil method below, first multiplying x by each of the components of the second equation, then the same with -4:

`x^3+6x^2-5x-4x^2-24x+20`

We simplify by combining like terms, giving us
`x^3+2x^2-29x+20`.
