Question

(x-2)(-5x^2+x)=(x)(-5x^2)+(x)(x)+(-2)(-5x^2)+(-2)(x) is an example of:

a.dividing two binomials
b.complex conjugates
c.foil
d.vertical multiplication

Answer 1

Is FOIL method

c is the correct answer

Answer 2

FOIL

Explanation:

`(x-2)(-5x^2+x)=(x)(-5x^2)+(x)(x)+(-2)(-5x^2)+(-2)(x)`

`(x-2)(-5x^2+x)`

On the right hand side , x is multiplied with
`-5x^2+x`

Then -2 is multiplied with
`-5x^2+x`

HEre x-2 is distributed inside the second parenthesis.

So FOIL method is applied to multiply both parenthesis

F- First terms are multiplied
`(x)(-5x^2)`

O-outside terms are multiplied
`(x)(x)`

I- Inside terms are multiplied
`(-2)(-5x^2)`

L- last terms are multiplied
`(-2)(x)`

FOIL method is applied
