8 x^{2} - 2 x = 15

x = - \frac{5}{4}, x = \frac{3}{2}

Decimal Notation

x = - 1.25, x = 1.5

Solution steps

8 x^{2} - 2 x = 15

Move

15

to the left side

8 x^{2} - 2 x - 15 = 0

Factor

8 x^{2} - 2 x - 15 : (4 x + 5) (2 x - 3)

(4 x + 5) (2 x - 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

4 x + 5 = 0 or 2 x - 3 = 0

Solve

4 x + 5 = 0 : x = - \frac{5}{4}

Solve

2 x - 3 = 0 : x = \frac{3}{2}

The solutions to the quadratic equation are:

x = - \frac{5}{4}, x = \frac{3}{2}

3 x^{2} - 15 = 33

3 v^{2} - 18 v - 48 = 0

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

5 x^{2} - 10 x = 15

y, x = y (2 - y)
