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

x = \frac{2}{3}, x = - 1

Decimal Notation

x = 0.66666 \dots, x = - 1

Solution steps

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

Move

2

to the right side

3 x^{2} + x = 2

Divide both sides by

3

\frac{3 x ^{2} + x}{3} = \frac{2}{3}

x^{2} + \frac{x}{3} = \frac{2}{3}

Rewrite in the form

(x + a)^{2} = b

(x + \frac{1}{6})^{2} = \frac{25}{36}

For

the solutions are

f (x) = a, - a

Solve

x + \frac{1}{6} = \frac{25}{36} : x = \frac{2}{3}

Solve

x + \frac{1}{6} = - \frac{25}{36} : x = - 1

The solutions to the quadratic equation are:

x = \frac{2}{3}, x = - 1

(1 + x)^{2} - 1 = 100 x^{2}

6 (x - 12) (x - 8) = 840

2 x^{2} - 19 x + 42 = 0

x^{2} - 3 (x + 4) = - 2 x

x^{2} + 5 x - 9 = 0
