Question

What is the product of the polynomials below?

(3x + 3)(6x + 9)

Answer 1

1. Solve using FOIL.
2. Add and/or subtract like terms.
Do you know how to solve using foil?

Answer 2

Simplifying
6x + 3 = 3x + 9

Reorder the terms:
3 + 6x = 3x + 9

Reorder the terms:
3 + 6x = 9 + 3x

Solving
3 + 6x = 9 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.
3 + 6x + -3x = 9 + 3x + -3x

Combine like terms: 6x + -3x = 3x
3 + 3x = 9 + 3x + -3x

Combine like terms: 3x + -3x = 0
3 + 3x = 9 + 0
3 + 3x = 9

Add '-3' to each side of the equation.
3 + -3 + 3x = 9 + -3

Combine like terms: 3 + -3 = 0
0 + 3x = 9 + -3
3x = 9 + -3

Combine like terms: 9 + -3 = 6
3x = 6

Divide each side by '3'.
x = 2

Simplifying
x = 2

Answer 3

no hahaha

Answer 4

i do not know how to use foil

Answer 5

(3x + 3)(6x + 9)
3x times 6x and 3x times 9, 3 times 6x and 3 times 9. That's FOIL
