Use the zero product property to find the solutions to the equation x^2 + x -30=12

Alla [95]

Answer:

The solutions are x = -7, 6.

Step-by-step explanation:

To find the solutions, move everything to one side of the equation so the equation is equal to 0. Then factor. Set the factors equal to 0 and solve for x.

$x^2 + x - 30 = 12\\x^2 + x -42=0\\(x+7)(x-6) = 0$

x+7 = 0

x = -7

and

x-6 = 0

x = 6

The solutions are x = -7, 6.

I have to solve for x

erastova [34]

The 3 angles of a triangle equal 180.

Subtract the bottom 2 angles from 180 and you get 50

So 8x + 2 = 50

Subtract 2 from both sides:

8x = 48

Divide both sides by 8

X = 6
