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

x = 4, x = - 2

Solution steps

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

Move

8

to the right side

x^{2} - 2 x = 8

Rewrite in the form

(x + a)^{2} = b

(x - 1)^{2} = 9

For

the solutions are

f (x) = a, - a

Solve

x - 1 = 9 : x = 4

Solve

x - 1 = - 9 : x = - 2

The solutions to the quadratic equation are:

x = 4, x = - 2

(n - 6) (n - 2) = - 9 n + 32

3 x^{2} - 16 x + 24 = 0

p, p^{1} \frac{v ^{1}}{t ^{1}} = p^{2} \frac{v ^{2}}{t ^{2}}

(x + 1) - x (x - 3) = 6

x^{2} + 20 x + 99 = 0
