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

x = \frac{4}{3}, x = - 2

Decimal Notation

x = 1.33333 \dots, x = - 2

Solution steps

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

Move

8

to the right side

3 x^{2} + 2 x = 8

Divide both sides by

3

\frac{3 x ^{2} + 2 x}{3} = \frac{8}{3}

x^{2} + \frac{2 x}{3} = \frac{8}{3}

Rewrite in the form

(x + a)^{2} = b

(x + \frac{1}{3})^{2} = \frac{25}{9}

For

the solutions are

f (x) = a, - a

Solve

x + \frac{1}{3} = \frac{25}{9} : x = \frac{4}{3}

Solve

x + \frac{1}{3} = - \frac{25}{9} : x = - 2

The solutions to the quadratic equation are:

x = \frac{4}{3}, x = - 2

x^{2} - 4 - (x - 1)^{2} - x = x (x - 1) - 8

x^{2} + b x + 8 = 0

40 \cdot 2.2455 + 150 (x^{2} - 6^{2}) - 196.2 (x - 6) = 0

0 = 0.1 \cdot 11 - (0.1 + 0.1) c - 6.05 \cdot 1 0^{- 4} c^{2} \cdot 25.4

- 3 x^{2} + 9 x + 4 = 0
