x^{2} - 9 x - 8 = 0

x = \frac{113 + 9}{2}, x = \frac{- 113 + 9}{2}

Decimal Notation

x = 9.81507 \dots, x = - 0.81507 \dots

Solution steps

x^{2} - 9 x - 8 = 0

Move

8

to the right side

x^{2} - 9 x = 8

Rewrite in the form

(x + a)^{2} = b

(x - \frac{9}{2})^{2} = \frac{113}{4}

For

the solutions are

f (x) = a, - a

Solve

x - \frac{9}{2} = \frac{113}{4} : x = \frac{113 + 9}{2}

Solve

x - \frac{9}{2} = - \frac{113}{4} : x = \frac{- 113 + 9}{2}

The solutions to the quadratic equation are:

x = \frac{113 + 9}{2}, x = \frac{- 113 + 9}{2}

A, E = \frac{1}{2} k A^{2}

5 x^{2} - 2 = 6

x \cdot (x + 1) = 20

4 x^{2} = 5 (4 x - 5)

420875.42 x^{2} + 296296.296 x - 750000 = 0
