- 2 x^{2} + 12 x - 13 = 0

x = \frac{5}{2} + 3, x = - \frac{5}{2} + 3

Decimal Notation

x = 4.58113 \dots, x = 1.41886 \dots

Solution steps

- 2 x^{2} + 12 x - 13 = 0

Move

13

to the right side

- 2 x^{2} + 12 x = 13

Divide both sides by

- 2

\frac{- 2 x ^{2} + 12 x}{- 2} = \frac{13}{- 2}

x^{2} - 6 x = - \frac{13}{2}

Rewrite in the form

(x + a)^{2} = b

(x - 3)^{2} = \frac{5}{2}

For

the solutions are

f (x) = a, - a

Solve

x - 3 = \frac{5}{2} : x = \frac{5}{2} + 3

Solve

x - 3 = - \frac{5}{2} : x = - \frac{5}{2} + 3

The solutions to the quadratic equation are:

x = \frac{5}{2} + 3, x = - \frac{5}{2} + 3

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

17 w^{2} + 4 w - 7 = 2 w^{2} + 6 w + 1

λ^{2} - 9 λ + 18 = 0

x^{2} = 2 4^{2} + 2 6^{2}

(D^{2} + 1) = 0
