Step-by-step explanation:

4x2 + 87x + 125 = 0

using the Quadratic Formula where

a = 4, b = 87, and c = 125

x= −b ± b2 − 4ac−−−−−−−√2a

x=−87 ± 872 − 4(4)(125)−−−−−−−−−−−−√2(4)

x= −87 ± 7569 − 2000−−−−−−−−−−√8

x= −87 ± 5569−−−−√8

The discriminant b2 − 4ac > 0

so, there are two real roots.

Cannot Simplify the Radical:

x = −87 ± 5569−−−−√8

x = −878 ± 5569−−−−√8

Simplify fractions and/or signs:

x = −878 ± 5569−−−−√8

which becomes x = −1.54678

x = −20.2032
