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

x = 3, x = 1

Solution steps

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

Move

8 x

to the left side

2 x^{2} - 8 x = - 6

Divide both sides by

2

\frac{2 x ^{2} - 8 x}{2} = \frac{- 6}{2}

x^{2} - 4 x = - 3

Rewrite in the form

(x + a)^{2} = b

(x - 2)^{2} = 1

For

the solutions are

f (x) = a, - a

Solve

x - 2 = 1 : x = 3

Solve

x - 2 = - 1 : x = 1

The solutions to the quadratic equation are:

x = 3, x = 1

x^{2} + 2 x - 3 = 0

6 x^{2} - 20 = 0

x, x^{2} + 10 x + 21 = 0

9 x^{2} - 5 = 11

10 x^{2} = 5
