- 7 (x + 8)^{2} + 4 = - 1

x = \frac{5}{7} - 8, x = - \frac{5}{7} - 8

Solution steps

- 7 (x + 8)^{2} + 4 = - 1

Move

4

to the right side

- 7 (x + 8)^{2} = - 5

Divide both sides by

- 7

(x + 8)^{2} = \frac{5}{7}

For

(g (x))^{2} = f (a)

the solutions are

g (x) = f (a), - f (a)

Solve

x + 8 = \frac{5}{7} : x = \frac{5}{7} - 8

Solve

x + 8 = - \frac{5}{7} : x = - \frac{5}{7} - 8

The solutions to the quadratic equation are:

x = \frac{5}{7} - 8, x = - \frac{5}{7} - 8

(2 n^{2} - 5 n - 6) + (- n^{2} - 3 n + 11)

0 = x^{2} + 6 x - 7

d^{2} + d - 7 = - 5

\frac{1}{2} (2)

8 x - x^{2} = 15
