x^{2} - 6 x - 16 = 0

x = 8, x = - 2

Solution steps

x^{2} - 6 x - 16 = 0

Move

16

to the right side

x^{2} - 6 x = 16

Rewrite in the form

(x + a)^{2} = b

(x - 3)^{2} = 25

For

the solutions are

f (x) = a, - a

Solve

x - 3 = 25 : x = 8

Solve

x - 3 = - 25 : x = - 2

The solutions to the quadratic equation are:

x = 8, x = - 2

x^{2} + 6 x - 4 = 0

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

x, x z + y z^{3} = 2 + x^{2} e^{y}

86 = 6 + 8 (x^{2})

x^{2} + 8 x + 4
