According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :

X² + 5x + 8

- B ± √ B2 - 4AC

x = ————————

In our case, A = 1

B = 5

C = 8

Accordingly, B2 - 4AC

= 25 - (32)

= - 7

Applying the quadratic formula :

-5 ± √ 7

x = —————

√ 7

Two real solutions:

x =(-5+√7)/2= 1.275

or:

x =(-5-√7)/2=-6.275
