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

x = 1, x = - 15

Solution steps

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

Move

15

to the right side

x^{2} + 14 x = 15

Rewrite in the form

(x + a)^{2} = b

(x + 7)^{2} = 64

For

the solutions are

f (x) = a, - a

Solve

x + 7 = 64 : x = 1

Solve

x + 7 = - 64 : x = - 15

The solutions to the quadratic equation are:

x = 1, x = - 15

w, 125 = w^{2} h

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

2 x^{2} - 8 x = 16

x^{2} = 3^{2} + 8^{2}

x, (x + 5)^{2} + (y - 5)^{2} = 0
