2 x^{2} - 8 x - 5 = 0

x = \frac{13}{2} + 2, x = - \frac{13}{2} + 2

Decimal Notation

x = 4.54950 \dots, x = - 0.54950 \dots

Solution steps

2 x^{2} - 8 x - 5 = 0

Move

5

to the right side

2 x^{2} - 8 x = 5

Divide both sides by

2

\frac{2 x ^{2} - 8 x}{2} = \frac{5}{2}

x^{2} - 4 x = \frac{5}{2}

Rewrite in the form

(x + a)^{2} = b

(x - 2)^{2} = \frac{13}{2}

For

the solutions are

f (x) = a, - a

Solve

x - 2 = \frac{13}{2} : x = \frac{13}{2} + 2

Solve

x - 2 = - \frac{13}{2} : x = - \frac{13}{2} + 2

The solutions to the quadratic equation are:

x = \frac{13}{2} + 2, x = - \frac{13}{2} + 2

x, 4 x^{2} - 21 x - 18 = 0

6 x^{2} - 6 x = 12

5 x^{2} = - 6 x - 1

352 = 7 x^{2} + 9

11 x^{2} - 13 x = x (8 - 3 x)
