Question

The sum of the roots of 8x^2- 2x

Answer 1

1/4

Explanation:

To find the roots of the expression, factor the expression by GCF.

`8x^2 - 2x\\2x(4x-1)`

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
