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

Factor

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

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

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

Solve

2 x - 5 = 0 : x = \frac{5}{2}

Solve

x + 3 = 0 : x = - 3

The solutions to the quadratic equation are:

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

3 (x - 6)^{2} + 4 = 0

lo g_{3} (81) = x^{2}

3 n^{2} - 4 n + 9 = 3

5 (x - 3)^{2} = 20

x^{2} + 8 + 12 = 0
