Answer:
x = 1, -5.56
Step-by-step explanation:
x^2 = -7x - 8
shift -7x and -8 to the other side . Remember when u shift minus changes into plus.
x^2 + 7x + 8 = 0
using quadratic equation formula
in quadratic equation one value comes positive and other comes in negative
a = 1 , b = 7 and c = 8
taking positive sign
x = (-b + ) /2*a
x = (-7 + ) /2*1
x = (-7 + ) /2
x = (-7 + )/ 2
x = -7 + 9 / 2
x = 2/2
x = 1
taking negative sign
(-b - ) /2*a
x = (-7 - ) /2*1
x = (-7 - ) /2
x = -7 - / 2
x = -7 - 4.12 / 2
x = -11.12/2
x = -5.56
therefore x = 1 , - 5.56
