x^{2} + 3 x - 1 = 0

x = \frac{13 - 3}{2}, x = \frac{- 13 - 3}{2}

Decimal Notation

x = 0.30277 \dots, x = - 3.30277 \dots

Solution steps

x^{2} + 3 x - 1 = 0

Move

1

to the right side

x^{2} + 3 x = 1

Rewrite in the form

(x + a)^{2} = b

(x + \frac{3}{2})^{2} = \frac{13}{4}

For

the solutions are

f (x) = a, - a

Solve

x + \frac{3}{2} = \frac{13}{4} : x = \frac{13 - 3}{2}

Solve

x + \frac{3}{2} = - \frac{13}{4} : x = \frac{- 13 - 3}{2}

The solutions to the quadratic equation are:

x = \frac{13 - 3}{2}, x = \frac{- 13 - 3}{2}

12 x^{2} + 25 x + 7 = 0

x^{2} - 1 - x - 22 = 0

2 x^{2} + 8 x - 15 = 0

x^{2} - 12 x - 49 = 0

4 x^{2} - 24 x - 64 = 0
