x^{2} - 5 x = 8

x = \frac{57 + 5}{2}, x = \frac{- 57 + 5}{2}

Decimal

x = 6.27491 \dots, x = - 1.27491 \dots

Solution steps

x^{2} - 5 x = 8

Rewrite in the form

(x + a)^{2} = b

(x - \frac{5}{2})^{2} = \frac{57}{4}

For

the solutions are

f (x) = a, - a

Solve

x - \frac{5}{2} = \frac{57}{4} : x = \frac{57 + 5}{2}

Solve

x - \frac{5}{2} = - \frac{57}{4} : x = \frac{- 57 + 5}{2}

The solutions to the quadratic equation are:

x = \frac{57 + 5}{2}, x = \frac{- 57 + 5}{2}

y, x^{2} + y^{2} = \frac{2 y}{x}

- 3 x^{2} + 12 x - 4 = - 12

5 a^{2} = 320

4 x^{2} + 1 = 8 x - 2

- 7 x^{2} + 5 x + 3 = 0
