x^{2} - 10 x + 15 = 0

x = 10 + 5, x = - 10 + 5

Decimal Notation

x = 8.16227 \dots, x = 1.83772 \dots

Solution steps

x^{2} - 10 x + 15 = 0

Move

15

to the right side

x^{2} - 10 x = - 15

Rewrite in the form

(x + a)^{2} = b

(x - 5)^{2} = 10

For

the solutions are

f (x) = a, - a

Solve

x - 5 = 10 : x = 10 + 5

Solve

x - 5 = - 10 : x = - 10 + 5

The solutions to the quadratic equation are:

x = 10 + 5, x = - 10 + 5

- x^{2} + 11 x - 28 = 0

2 x^{2} - 12 x + 6 = 0

s^{2} + 40 s + 400 = 0

- 5 (- x + 3) - 2 = \frac{1}{2} x (x + 2) - \frac{19}{2}

x, 2 x^{2} + 4 x - 3 = 0
