Question

solve the quadra
tic polynomial 4x^2+87x+125​

Answer 1

Answer:

• 4x²+87+125 you should split the terms

Answer 2

Answer:

x=−1.54678

 

x=−20.2032

Step-by-step explanation:

4x^2+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
