k^{2} - 18 k + 8 = - 9

k = 17, k = 1

Solution steps

k^{2} - 18 k + 8 = - 9

Move

8

to the right side

k^{2} - 18 k = - 17

Rewrite in the form

(x + a)^{2} = b

(k - 9)^{2} = 64

For

the solutions are

f (x) = a, - a

Solve

k - 9 = 64 : k = 17

Solve

k - 9 = - 64 : k = 1

The solutions to the quadratic equation are:

k = 17, k = 1

x^{2} - 5 x - 2 = 4

r^{2} + 4 r - 60 = 0

2 x^{2} - 2 x + 12 = 0

4 x^{2} + 30 x - 16 = 0

x, x^{2} + x^{2} = (x + y)^{2}
