8 x^{2} + 10 x - 7 = 0

x = \frac{1}{2}, x = - \frac{7}{4}

Decimal Notation

x = 0.5, x = - 1.75

Solution steps

8 x^{2} + 10 x - 7 = 0

Move

7

to the right side

8 x^{2} + 10 x = 7

Divide both sides by

8

\frac{8 x ^{2} + 10 x}{8} = \frac{7}{8}

x^{2} + \frac{5 x}{4} = \frac{7}{8}

Rewrite in the form

(x + a)^{2} = b

(x + \frac{5}{8})^{2} = \frac{81}{64}

For

the solutions are

f (x) = a, - a

Solve

x + \frac{5}{8} = \frac{81}{64} : x = \frac{1}{2}

Solve

x + \frac{5}{8} = - \frac{81}{64} : x = - \frac{7}{4}

The solutions to the quadratic equation are:

x = \frac{1}{2}, x = - \frac{7}{4}

x^{2} - 6 x + 9 = 0

5 x^{2} - 3 x = 9

x (x + 5) + x (x - 2) = 5 x + 4

3 x^{2} = x + 2

x^{2} + 8 x + 36 = - 8 x
