Answer 2

Step-by-step explanation:

STEP 1

Expand the following:

(x + 3)^2

STEP 2

Hint: | Multiply x + 3 and x + 3 together using FOIL.

(x + 3) (x + 3) = (x) (x) + (x) (3) + (3) (x) + (3) (3):

x x + 3 x + 3 x + 3 3

STEP 3

Hint: | Combine products of like terms.

x x = x^2:

x^2 + 3 x + 3 x + 3 3

STEP 4

Hint: | Multiply 3 and 3 together.

3×3 = 9:

x^2 + 3 x + 3 x + 9

STEP 5

Hint: | Group like terms in x^2 + 3 x + 3 x + 9.

Grouping like terms, x^2 + 3 x + 3 x + 9 = x^2 + (3 x + 3 x) + 9:

x^2 + (3 x + 3 x) + 9

STEP 6

Hint: | Add like terms in 3 x + 3 x.

3 x + 3 x = 6 x:

Answer: x^2 + 6 x + 9
