Question

What is (2x + 3) to the 2 power

Answer 1

4x^2+12x+9

Explanation:

use FOIL (first, inner, outer, last)

(2x+3)(2x+3)

4x^2+6x+6x+9

then simplify

Answer 2

4x² + 12x + 9

Explanation:

Simplify. Expand:

(2x + 3)² = (2x + 3)(2x + 3)

Use the FOIL method to solve.

FOIL =

First

Outside

Inside

Last

Multiply:

(2x)(2x) = 4x²

(2x)(3) = 6x

(3)(2x) = 6x

(3)(3) = 9

Combine like terms:

4x² + 6x + 6x + 9 = 4x² + (6x + 6x) + 9 = 4x² + 12x + 9

4x² + 12x + 9 is your answer.
