Question

What are the solutions of x2=-7x-8

Answer 1

Answer:

x^2 = -7x -8

x^2 +7x +8 = 0

D = 49 -32 = 17

x_1,2 = (-7+/-sqrt17)/2 = (-7-sqrt17)/2 and (-7+sqrt17)/2

Step-by-step explanation:

Answer 2

Answer:

x = $\frac{1}{2}$ (-7±√17)

Step-by-step explanation:

x² = -7x - 8

x² + 7x + 8 = 0

Using the quadratic formula, with a=1, b = 7 and c=8,

you will get x = $\frac{1}{2}$ (-7±√17)
