4 x^{2} + 15 x = 4

x = \frac{1}{4}, x = - 4

Decimal Notation

x = 0.25, x = - 4

Solution steps

4 x^{2} + 15 x = 4

Move

4

to the left side

4 x^{2} + 15 x - 4 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 15 \pm 1 5 ^{2} - 4 \cdot 4 ( - 4 )}{2 \cdot 4}

1 5^{2} - 4 \cdot 4 (- 4) = 17

x_{1, 2} = \frac{- 15 \pm 17}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- 15 + 17}{2 \cdot 4}, x_{2} = \frac{- 15 - 17}{2 \cdot 4}

x = \frac{- 15 + 17}{2 \cdot 4} : \frac{1}{4}

x = \frac{- 15 - 17}{2 \cdot 4} : - 4

The solutions to the quadratic equation are:

x = \frac{1}{4}, x = - 4

\frac{\frac{1}{2}}{\frac{1}{6}}

- x + 4 > 8

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

\frac{2}{3} - \frac{1}{4}

\frac{π}{3} - \frac{π}{6}
