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

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

Decimal Notation

x = 2.5, x = - 3

Solution steps

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

Move

15

to the right side

2 x^{2} + x = 15

Divide both sides by

2

\frac{2 x ^{2} + x}{2} = \frac{15}{2}

x^{2} + \frac{x}{2} = \frac{15}{2}

Rewrite in the form

(x + a)^{2} = b

(x + \frac{1}{4})^{2} = \frac{121}{16}

For

the solutions are

f (x) = a, - a

Solve

x + \frac{1}{4} = \frac{121}{16} : x = \frac{5}{2}

Solve

x + \frac{1}{4} = - \frac{121}{16} : x = - 3

The solutions to the quadratic equation are:

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

3 s^{2} - 13 s + 4 = 0

2 m^{2} - m - 8 = 0

7 x^{2} + 2 x = 0

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

(6 x) (x - 10) = 0
