x^{2} + 6 x + 8 = 0

x = - 2, x = - 4

Solution steps

x^{2} + 6 x + 8 = 0

Move

8

to the right side

x^{2} + 6 x = - 8

Rewrite in the form

(x + a)^{2} = b

(x + 3)^{2} = 1

For

the solutions are

f (x) = a, - a

Solve

x + 3 = 1 : x = - 2

Solve

x + 3 = - 1 : x = - 4

The solutions to the quadratic equation are:

x = - 2, x = - 4

x, (x + y)^{3} = x^{3} + y^{3}

6 x^{2} + 125 = x^{2}

2 d^{2} + 5 d - 5 = - d

(x + 1) (x - 2) + x^{2} = 0

y, x^{3} y^{2} = 2 x^{2} + y^{2}
