x^{2} - 18 x + 68 = 0

x = 13 + 9, x = - 13 + 9

Decimal Notation

x = 12.60555 \dots, x = 5.39444 \dots

Solution steps

x^{2} - 18 x + 68 = 0

Move

68

to the right side

x^{2} - 18 x = - 68

Rewrite in the form

(x + a)^{2} = b

(x - 9)^{2} = 13

For

the solutions are

f (x) = a, - a

Solve

x - 9 = 13 : x = 13 + 9

Solve

x - 9 = - 13 : x = - 13 + 9

The solutions to the quadratic equation are:

x = 13 + 9, x = - 13 + 9

a^{2} + 7^{2} = 9^{2}

16 x^{2} = 64

x^{2} = 3 x^{2}

X^{2} = 169

n^{2} - 30 n = 0
