2 x^{2} + 8 x - 24 = 0

x = 2, x = - 6

Solution steps

2 x^{2} + 8 x - 24 = 0

Move

24

to the right side

2 x^{2} + 8 x = 24

Divide both sides by

2

\frac{2 x ^{2} + 8 x}{2} = \frac{24}{2}

x^{2} + 4 x = 12

Rewrite in the form

(x + a)^{2} = b

(x + 2)^{2} = 16

For

the solutions are

f (x) = a, - a

Solve

x + 2 = 16 : x = 2

Solve

x + 2 = - 16 : x = - 6

The solutions to the quadratic equation are:

x = 2, x = - 6

c^{2} = 7^{2} + 1 0^{2}

5 x^{2} + 9 x = 6

(x + 8) (x - 7) = 2

9 x^{2} + 29 x + 25 = 0

x^{2} + 23 + 120 = 0
