10 x^{2} - 9 x - 9 = 0

x = \frac{3}{2}, x = - \frac{3}{5}

Decimal Notation

x = 1.5, x = - 0.6

Solution steps

10 x^{2} - 9 x - 9 = 0

Move

9

to the right side

10 x^{2} - 9 x = 9

Divide both sides by

10

\frac{10 x ^{2} - 9 x}{10} = \frac{9}{10}

x^{2} - \frac{9 x}{10} = \frac{9}{10}

Rewrite in the form

(x + a)^{2} = b

(x - \frac{9}{20})^{2} = \frac{441}{400}

For

the solutions are

f (x) = a, - a

Solve

x - \frac{9}{20} = \frac{441}{400} : x = \frac{3}{2}

Solve

x - \frac{9}{20} = - \frac{441}{400} : x = - \frac{3}{5}

The solutions to the quadratic equation are:

x = \frac{3}{2}, x = - \frac{3}{5}

(x + 5)^{2} = 7 (x + 5)

t, h = t^{2} + 2 t

2 x^{2} - 9 = 12 x

v^{2} - 3 = - 16

X^{2} - 6 X + 2 = 0
