Select the approximate values of x that are solutions to f(x) = 0, where f(x) = -4x2 + 6x + 3.

Question

Select the approximate values of x that are solutions to f(x) = 0, where
f(x) = -4x2 + 6x + 3.

Answer 1

-4x²+6x+3

(-6+√36+48)/-8

(-6+√84)/-8

(-6+2√21)/-8

(-3+√21)/-4

(-3+4.582575)/-4

1.582575/-4=-0.395643

-7.582575/-4=1.895643
