Find the product: (x + 5)2

Question

12 Answer:

Referring to the figure, find an expression for the area.

13 Answer:

Use the zero-product property to solve the equation:
(x + 4)(x - 2) = 0
*NOTE: Applicable to this and all other questions--
For any solution that involves two answers, type one
answer separated by a comma and then the other answer.

Answer 1

Multiply 2 by each term in the parenthesis:

12. 2(X+5) = 2*X + 2*5 = 2X + 10.

13. (X+4)(X-2) = 0.

X+4 = 0,
X = -4.

(X-2) = 0,
X = 2.

Solution: X = -4, OR X = 2.
