Question

My teacher dis the first one​

Answer 1

x² + 11x + 30

Explanation:

Solve using the FOIL method. The FOIL method is:

FOIL =

First

Outside

Inside

Last

, and is the order in which you do the problem.

(x + 5)(x + 6)

Follow FOIL. First, solve First (multiply x with x)

(x)(x) = x²

Next, multiply Outside (multiply x with 6)

(x)(6) = 6x

Then, multiply Inside (multiply 5 with x)

(5)(x) = 5x

Finally, multiply Last (multiply 5 with 6)

(5)(6) = 30

Combine like terms (terms with the same amount of variables, and the same variables)

x² + 6x + 5x + 30

x² + (6x + 5x) + 30

x² + 11x + 30

x² + 11x + 30 is your answer.
