X^2+ 14x = -33
Quadratic equation

x = -3, -11

Step-by-step explanation:

First, factor

Get all the terms on one side by adding 33 to both sides:

now, you want to find two numbers that add up to 14 and multiply to 33.

those numbers would be 3 and 11.

so you can then make it:

you know that either x + 3 or x + 11 = 0,

so you can say:

x + 3 = 0

x = -3

ork

x + 11 = 0

x = -11

so x = -3, -11.
