The quadratic formula is used to solve for the roots of the equation:
x = (-b ± √(b^2 - 4ac)) / 2a
Plugging in the values of a=1, b=2, and c=-8 into the formula:
x = (-2 ± √(2^2 - 41(-8))) / 2*1x = (-2 ± √(4 + 32)) / 2x = (-2 ± √36) / 2x = (-2 ± 6) / 2
Therefore, the roots of the equation are:
x1 = (-2 + 6) / 2 = 4 / 2 = 2x2 = (-2 - 6) / 2 = -8 / 2 = -4
So, the solutions to the equation 1x^2 + 2x - 8 = 0 are x = 2 and x = -4.
