Answer:

[tex] {x}^{2} + x - 4[/tex]

Explanation:

Using the foil method the answer is x²+x-4

What is FOIL method?

The FOIL method lets you multiply two binomials in a particular order. The letters in FOIL refer to two terms (one from each of two binomials) multiplied together in a certain order: First, Outer, Inner, and Last.

F-first

  • The first is to multiply x from the first binomial to x from the second binomial.

O-outer

  • The outer is to multiply x from the first binomial to -2 from the second binomial.

I-inner

  • The inner is to multiply 2 from the first binomial to x from the second binomial.

L-last

  • The last is to multiply 2 from the first binomial to -2 from the second binomial.

Solution:

First: x × x = x²

Outer: x × -2 = -2x

Inner: 2 × x = 2x

Last: 2 × -2 = -4

Add:

x² -2x

+ 2x -4

--------------------------

x² + x -4
