It doesn't matter. It can't be correct either way.
The range says that 'x' is a number between 90 and 180.
Neither -0.6 nor +0.6 is between 90 and 180.
Answer:
1/4
Step-by-step explanation:
To find the roots of the expression, factor the expression by GCF.

The roots are the factors set equal to 0 and solved for x.
2x = 0
x=0
4x-1 = 0
x = 1/4
The sum is the addition of the two roots 0 + 1/4 = 1/4
Additive Inverse. -5 and 5 are opposites.
