x^{2} - x - 3 = 0

x = \frac{13 + 1}{2}, x = \frac{- 13 + 1}{2}

Decimal Notation

x = 2.30277 \dots, x = - 1.30277 \dots

Solution steps

x^{2} - x - 3 = 0

Move

3

to the right side

x^{2} - x = 3

Rewrite in the form

(x + a)^{2} = b

(x - \frac{1}{2})^{2} = \frac{13}{4}

For

the solutions are

f (x) = a, - a

Solve

x - \frac{1}{2} = \frac{13}{4} : x = \frac{13 + 1}{2}

Solve

x - \frac{1}{2} = - \frac{13}{4} : x = \frac{- 13 + 1}{2}

The solutions to the quadratic equation are:

x = \frac{13 + 1}{2}, x = \frac{- 13 + 1}{2}

3 x^{2} - 18 = 2 x + 1

m^{2} + 12 m + 20 = 0

- 3 x^{2} - 120 = 0

4 x^{2} + 3 x - 22 = 0
