add-36 to dufference of -8 and 18
Answers
Answer:
Step-by-step explanation:
x2 + 30x + 180 = -36
Add 36 to both sides of the equation.
x2 + 30x + 216 = 0
What two numbers add to 30 and multiply to 216 ? +12 and +18
So the left side of the equation factors like this...
(x + 12)(x + 18) = 0
Set each factor equal to zero and solve for x .
x + 12 = 0 or x + 18 = 0
x = -12 x = -18
The roots of the equation are -12 and -18 .
The nonnegative difference between -12 and -18 is (-12) - (-18) = -12 + 18 = 6
