Solve x2 + 10x + 12 = 36 for x.

Okay, So We Have The Equation:

2x + 10x + 12 = 36.

Combine The 2x and 10x.

12x + 12 = 36.

Subtract 12 From Both Sides.

12x = 36 - 12

36 - 12 = 24.

12x = 24

Divide.

12x/12 = 1x = X

X = 24/12

24/12 = 2

X = 2.

Well lets start with x = 1 so 1 x 2 = 2 + 10 x 1 = 10 + 12

2 + 10 + 12 = 24 so x doesn't equal 1

lets try x = 2

2 x 2 = 4

10 x 2 = 20

4 + 20 + 12 = 36 so X = 2
