Answer 1

Answer:

answer is here ........

Answer 2

Answer:

Answer:

x=−22x=−102

x=−1

x=−5

Find the Solution for

1x2+6x+5=0

using the Quadratic Formula where

a = 1, b = 6, and c = 5

x=−b±b2−4ac−−−−−−−√2a

x=−6±62−4(1)(5)−−−−−−−−−−√2(1)

x=−6±36−20−−−−−−√2

x=−6±16−−√2

The discriminant b2−4ac>0

so, there are two real roots.

Simplify the Radical:

x=−6±42

x=−22x=−102

which becomes

x=−1

x=−5
