Question

Select the approximate values of x that are solutions to f(x) = 0, where
f(x) = -5x2 + 9x + 7.

{–0.71, 1.29}

{-5, 9}

{–1.80, –1.40}

{–0.59, 2.39}

Answer 1

-5x2 + 9x + 7 = 0

multiply both sides by -1

5x2 - 9x - 7 = 0

Applying the solution for the quadratic we have:

x1 = -0.59 and x2 = 2.39
