The quadratic formula is:
m = (-b ± sqrt(b^2 - 4ac)) / 2a
In this equation, a = 8, b = 13, and c = -7. Substitute these values into the quadratic formula and simplify.
m = (-13 ± sqrt(13^2 - 4(8)(-7))) / 2(8)
m = (-13 ± sqrt(169 + 224)) / 16
m = (-13 ± sqrt(393)) / 16
Therefore, the solutions are:
m ≈ -0.893 or m ≈ 0.68
m = (-b ± sqrt(b^2 - 4ac)) / 2a
