x^{2} - 4 x - 45 = 0

x = 9, x = - 5

Solution steps

x^{2} - 4 x - 45 = 0

Move

45

to the right side

x^{2} - 4 x = 45

Rewrite in the form

(x + a)^{2} = b

(x - 2)^{2} = 49

For

the solutions are

f (x) = a, - a

Solve

x - 2 = 49 : x = 9

Solve

x - 2 = - 49 : x = - 5

The solutions to the quadratic equation are:

x = 9, x = - 5

- 2 x^{2} + 8 x - 3 = 4

2 x^{2} + 6 x + 3 = 0

x^{2} + 445 x - 2225 = 0

x, 4 x^{2} + 4 y^{2} = z^{2}

- 3 x^{2} - 3 x + 10
