2 x^{2} + 8 x + 134 = 0

x = 37 i - 2, x = - 37 i - 2

Solution steps

2 x^{2} + 8 x + 134 = 0

Move

134

to the right side

2 x^{2} + 8 x = - 134

Divide both sides by

2

\frac{2 x ^{2} + 8 x}{2} = \frac{- 134}{2}

x^{2} + 4 x = - 67

Rewrite in the form

(x + a)^{2} = b

(x + 2)^{2} = - 63

For

the solutions are

f (x) = a, - a

Solve

x + 2 = - 63 : x = 37 i - 2

Solve

x + 2 = - - 63 : x = - 37 i - 2

The solutions to the quadratic equation are:

x = 37 i - 2, x = - 37 i - 2

20 x^{2} - 5 x - 12 = 0

x^{2} + 12 x - 8 = 0

- 4 x^{2} - 6 x + 1 = 0

(5 x - 9)^{2} = 1296

- 5 x^{2} - 87 x - 391 = 3 x - 63 x - 6
