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

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

Decimal

x = 2.5, x = - 2

Solution steps

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

Move

10

to the right side

2 x^{2} - x = 10

Divide both sides by

2

\frac{2 x ^{2} - x}{2} = \frac{10}{2}

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

Rewrite in the form

(x + a)^{2} = b

(x - \frac{1}{4})^{2} = \frac{81}{16}

For

the solutions are

f (x) = a, - a

Solve

x - \frac{1}{4} = \frac{81}{16} : x = \frac{5}{2}

Solve

x - \frac{1}{4} = - \frac{81}{16} : x = - 2

The solutions to the quadratic equation are:

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

(x) = x^{2} - 6 x + 8

(k + 2) x^{2} + 2 k x + k + 1 = 0

x^{2} - 12 x + 33 = 0

(a - 3)^{2} = 12

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