3 x^{2} + 10 x - 8 = 0

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

Decimal Notation

x = 0.66666 \dots, x = - 4

Solution steps

3 x^{2} + 10 x - 8 = 0

Move

8

to the right side

3 x^{2} + 10 x = 8

Divide both sides by

3

\frac{3 x ^{2} + 10 x}{3} = \frac{8}{3}

x^{2} + \frac{10 x}{3} = \frac{8}{3}

Rewrite in the form

(x + a)^{2} = b

(x + \frac{5}{3})^{2} = \frac{49}{9}

For

the solutions are

f (x) = a, - a

Solve

x + \frac{5}{3} = \frac{49}{9} : x = \frac{2}{3}

Solve

x + \frac{5}{3} = - \frac{49}{9} : x = - 4

The solutions to the quadratic equation are:

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

y^{2} + 4 y - 6 = 0

- 2 x^{2} - 20 x - 50 = 0

4.905 t^{2} - 90 t - 150 = 0

3 x^{2} + 3 = 30

x, 2 x^{2} + 2 y^{2} + 2 x + 2 = 0
