x^{2} - 10 x + 9 = 0

x = 9, x = 1

Solution steps

x^{2} - 10 x + 9 = 0

Move

9

to the right side

x^{2} - 10 x = - 9

Rewrite in the form

(x + a)^{2} = b

(x - 5)^{2} = 16

For

the solutions are

f (x) = a, - a

Solve

x - 5 = 16 : x = 9

Solve

x - 5 = - 16 : x = 1

The solutions to the quadratic equation are:

x = 9, x = 1

4 x^{2} + 20 x + 23 = 0

x^{2} + 18 x + 42 = 0

3 x^{2} + 10 x + 9 = 0

1 - 5 x + x^{2} + 2 x = 1

(x + 1) (x - 2) = 3
