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

x = - 1, x = - \frac{3}{2}

Decimal Notation

x = - 1, x = - 1.5

Solution steps

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

Move

3

to the right side

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

Divide both sides by

2

\frac{2 x ^{2} + 5 x}{2} = \frac{- 3}{2}

x^{2} + \frac{5 x}{2} = - \frac{3}{2}

Rewrite in the form

(x + a)^{2} = b

(x + \frac{5}{4})^{2} = \frac{1}{16}

For

the solutions are

f (x) = a, - a

Solve

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

Solve

x + \frac{5}{4} = - \frac{1}{16} : x = - \frac{3}{2}

The solutions to the quadratic equation are:

x = - 1, x = - \frac{3}{2}

x, 9 x^{2} - 12 x y + 4 y^{2} + 38 x - 60 y + 121 = 0

- 6 x^{2} + 24 x + 30 = 0

3 x^{2} = 14 x + 2

4 x^{2} - 1 = 6 x

x, 3 x^{2} - 8 x y + 6 y^{2} - 5 x - 5 y + 20 = 0
