2 x^{2} + 5 x + 2 = 0

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

Decimal Notation

x = - 0.5, x = - 2

Solution steps

2 x^{2} + 5 x + 2 = 0

Move

2

to the right side

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

Divide both sides by

2

\frac{2 x ^{2} + 5 x}{2} = \frac{- 2}{2}

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

Rewrite in the form

(x + a)^{2} = b

(x + \frac{5}{4})^{2} = \frac{9}{16}

For

the solutions are

f (x) = a, - a

Solve

x + \frac{5}{4} = \frac{9}{16} : x = - \frac{1}{2}

Solve

x + \frac{5}{4} = - \frac{9}{16} : x = - 2

The solutions to the quadratic equation are:

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

\frac{1}{2} x^{2} + 3 x = - 12

x^{2} + 5 x - 1 = 0

- 3 x^{2} + 6 x - 1

\frac{1}{3} x^{2} + 3 x - 4 = - 4

x, x \cdot (x - y) + y \cdot (y - z) + z \cdot (z - x) = 1
