multiply x+2 by x+2 is equal to?

Question

     x+2

x    x+2

 

Answer 1

(x + 2)(x + 2)

 

When we multiply two binomials, we use a method known as FOIL.

 

F ---> first terms

O ---> outer terms

I ----> inner terms

L ----> last terms

 

 

Step F

 

Multiply the first terms in both binomial.

 

x * x = x²

 

 

Step O

 

Multiply the first term in the first binomial by the last term in the second binomial.

 

x * 2 = 2x

 

 

Step I

 

Multiply the last term in the first binomial by the first term in the second binomial.

 

2 * x = 2x

 

 

Step L

 

Multiply the last terms in both binomials.

 

2 * 2 = 4

 

 

Last step is to combine the results of the previous steps.

 

x² + 2x + 2x + 4 =

 

x² + 4x + 4

Answer 2

You can distribute or use FOIL (First, Outer, Inner Last)

        x + 2

        x + 2        

      2x + 4

x²+2x       

x² +4x +4     answer

 

 

(x + 2)(x + 2) = x² +4x +4   answer
