Xsquare + 10x + 16 equals 0

X^2+10x+16＝0

First, you find factors of 16.

1 x 16

2 x 8

4 x 4

Next, you find which of the factor pairs adds up to 10 (from the 10x). In this case, 2 x 8 because 2 times 8 is 16 and 2 plus 8 is 10.

Then, the equation will be written out as: (x+2) (x+8). Take those two equations and set them equal to 0, and then solve.

x+2＝0

-2 - 2

x＝-2

x+8＝0

-8 - 8

x＝-8

So, your answers are x＝-2 and x＝-8. You can check by plugging in those two numbers as x.
