X² + 6x - 71=0
PLEASE HELP

x = -3 + 4√5    or    x = -3 - 4√5

Step-by-step explanation:

Hi, I'm going to assume this needs to be solved with the quadratic formula. Please LMK if otherwise. You can use mathpapa.com for help on these sort of questions, or symbolab.

a = 1, b = 6, c = -71

x^2 + 6x + -71 = 0

x= −b±√b2−4ac

            2a

Plug in the numbers..

x = −(6)±√(6)^2 −4(1)(−71)

                  2(1)

Simplify..

x = −6±√320

            2

Your answer would be

x = -3 + 4√5

or x = -3 - 4√5

Please let me know if you need it solved in a different way. :)

probably .5

i can on others if necessary.
