Answer:
The roots are -1/2 and 3/4

Step-by-step explanation:
The general form of the quadratic equation is:
ax² + bx + c = 0
The given equation is:
8x² -2x - 2 = 1
This can be rewritten as:
8x² - 2x - 3 = 0
By comparison, we would find that:
a = 8
b = -2
c = -3

Now, to get the roots of the equation, we would use the quadratic formula sown in the attached image

Substituting in the formula, we would find that:
either x =
(-(-2) + √((-2)^2 - 4(8)(-3)) )/(2(8)) = (3)/(4)

or x =
(-(-2) - √((-2)^2 - 4(8)(-3)) )/(2(8)) = (-1)/(2)

This means that the roots are:
-1/2 and 3/4

Hope this helps :)
