Mathematics
1 answer:
Reil [10]3 years ago
4 0

Step-by-step explanation:

Add one to both sides of the equation:

x^2 - 2x + 1 = 15 + 1

\Rightarrow (x - 1)^2 = 16

Taking the square root of the equation above, we get

x - 1 = \pm 4

or

x = 1 \pm 4 = 5, -3

tino4ka555 [31]

Hello there! :)

Answer:

First choice, (x + 2) and (x - 6).

Step-by-step explanation:

To solve for the dimensions, recall that the formula for the volume of a rectangle is:

A = l × w

Simply factor x² -4 - 12. Find two numbers that add up to -4 and multiply into -12.

2, -6 satisfy these conditions. Use these numbers to write this equation in factored form:

(x + 2) (x - 6). Thus, the first option is the correct answer.
