x^{2} - 9 x - 26 = 0

x = \frac{185 + 9}{2}, x = \frac{- 185 + 9}{2}

Decimal Notation

x = 11.30073 \dots, x = - 2.30073 \dots

Solution steps

x^{2} - 9 x - 26 = 0

Move

26

to the right side

x^{2} - 9 x = 26

Rewrite in the form

(x + a)^{2} = b

(x - \frac{9}{2})^{2} = \frac{185}{4}

For

the solutions are

f (x) = a, - a

Solve

x - \frac{9}{2} = \frac{185}{4} : x = \frac{185 + 9}{2}

Solve

x - \frac{9}{2} = - \frac{185}{4} : x = \frac{- 185 + 9}{2}

The solutions to the quadratic equation are:

x = \frac{185 + 9}{2}, x = \frac{- 185 + 9}{2}

y, - x^{2} y^{2} = k

x^{2} + 14 x - 15 = 0

w, 125 = w^{2} h

4 x^{2} - 18 x + 414 = - 2 x^{2} + 84 x + 162

2 x^{2} - 8 x = 16
