5 x^{2} - 10 x - 75 = 0

x = 5, x = - 3

Solution steps

5 x^{2} - 10 x - 75 = 0

Move

75

to the right side

5 x^{2} - 10 x = 75

Divide both sides by

5

\frac{5 x ^{2} - 10 x}{5} = \frac{75}{5}

x^{2} - 2 x = 15

Rewrite in the form

(x + a)^{2} = b

(x - 1)^{2} = 16

For

the solutions are

f (x) = a, - a

Solve

x - 1 = 16 : x = 5

Solve

x - 1 = - 16 : x = - 3

The solutions to the quadratic equation are:

x = 5, x = - 3

s^{2} + 6 s + 36.9 = 0

- 2 x^{2} + 3 x - 1

- p^{2} + 2 p + 3 = 0

15 + 2 (2.5 - x) = 11 + x^{2}

x, (x - 2)^{2} + (y - 3)^{2} = 0
