x^{2} - 18 x + 65 = 0

x = 13, x = 5

Solution steps

x^{2} - 18 x + 65 = 0

Move

65

to the right side

x^{2} - 18 x = - 65

Rewrite in the form

(x + a)^{2} = b

(x - 9)^{2} = 16

For

the solutions are

f (x) = a, - a

Solve

x - 9 = 16 : x = 13

Solve

x - 9 = - 16 : x = 5

The solutions to the quadratic equation are:

x = 13, x = 5

x^{2} + x - e = 0

2 x^{2} - 6 x = 6 \cdot 2 - 8 x

6 x^{2} + 24 \times 18 = 0

y, z = \frac{y ^{2}}{4}

\frac{1}{3} v^{2} + 27 = 12
