Question

simplify with foil (w + x )(w + x )

Answer 1

Foil is an acronym that stands for:

First

Outside

Inside

Last

First:

(w + x )(w + x ) = $w^{2}$

Outside:

(w + x )(w + x ) = wx

Inside:

(w + x )(w + x ) = wx

Last:

(w + x )(w + x ) = $x^{2}$

so...

$w^{2}$ + wx + wx + $x^{2}$

$w^{2} +x^{2} + 2xw$

Hope this helped!

Answer 2

Answer: $x^2+2wx+w^2$

Step-by-step explanation:

Given the expression $(w + x )(w + x )$ , which indicates the multiplication of two binomials, you can simplify it with FOIL:

Multiply:

The first terms (w by w).

The outside terms  (w by x).

The inside terms together (x by w).

The last terms together (x by x).

Then, you get:

$(w + x )(w + x )=(w)(w)+(w)(x)+(x)(w)+(x)(x)=w^2+wx+wx+x^2$

Adding like terms, you get:

$x^2+2wx+w^2$
