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

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

Decimal Notation

x = - 2, x = 2.5

Solution steps

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

Factor

2 x^{2} - x - 10 : (x + 2) (2 x - 5)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

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

Solve

x + 2 = 0 : x = - 2

Solve

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

The solutions to the quadratic equation are:

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

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

x^{2} + 3 x + 30 = 0

(x - 7) (5 x + 8) = 0

- \frac{1}{500} (x - 100)^{2} + 20 = 0

2 x^{2} + 2 x + 11
