(-5+x)(x+ 4) please help and show work

x^2-x-20

Step-by-step explanation:

(-5+x)(x+ 4)

Follow these FOIL to get to the answer!

First - combine the first number or letter in each parenthesis.

(-5+x)(x+ 4)

-5x

Outer - combine the outer number or letter in each parenthesis.

(-5+x)(x+ 4)

-20

Inner - combine the inner number or letter in each parenthesis.

(-5+x)(x+ 4)

x^2

Last - combine the last number or letter in each parenthesis.

(-5+x)(x+ 4)

4x

Now combine each FOIL answer to get to the answer!(and remember to do it in order)

Step-by-step explanation:

Use FOIL (a + b)(c + d) = ac + ad + bc + bd:

(-5 + x)(x + 4)

= (-5)(x) + (-5)(4) + (x)(x) + (x)(4)

= - 5x + (-20) + x² + 4x         combine like terms

= x² + (-5x + 4x) + (-20)

= x² + (-1x) + (-20)

= x² -x - 20

answer: the answer is 35%
