2 x^{2} - 7 x - 15 = 0

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

Decimal Notation

x = 5, x = - 1.5

Solution steps

2 x^{2} - 7 x - 15 = 0

Move

15

to the right side

2 x^{2} - 7 x = 15

Divide both sides by

2

\frac{2 x ^{2} - 7 x}{2} = \frac{15}{2}

x^{2} - \frac{7 x}{2} = \frac{15}{2}

Rewrite in the form

(x + a)^{2} = b

(x - \frac{7}{4})^{2} = \frac{169}{16}

For

the solutions are

f (x) = a, - a

Solve

x - \frac{7}{4} = \frac{169}{16} : x = 5

Solve

x - \frac{7}{4} = - \frac{169}{16} : x = - \frac{3}{2}

The solutions to the quadratic equation are:

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

\frac{x ^{2}}{2} - \frac{3 x}{4} = 0

120000 = 350 x - 0.25 x^{2}

x^{2} + 6 x - 36 = 0

y^{2} + 4 y - 3 = 0

3 x^{2} + 5 x + \frac{3}{4} = 0
