Question 623354
7(2 + 3t)^2

We use the order of operations - PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

(2 + 3t)^2

We Multiply the above using the FOIL Method:

(2 + 3t)(2 + 3t)

2 * 2 = 4

2 * 3t = 6t

3t * 2 = 6t

3t * 3t = 9t^2

4 + 6t + 6t + 9t^2

Combine like terms:

6t + 6t = 12t

4 + 12t + 9t^2

7(4 + 12t + 9t^2)

7 * 4 = 28

7 * 12t = 84t

7 * 9t^2 = 63t^2

The Answer:

28 + 84t + 63t^2

or to put it in the correct order:

63t^2 + 84t + 28
