4 x^{2} - 16 x + 15 = 0

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

Decimal

x = 2.5, x = 1.5

Solution steps

4 x^{2} - 16 x + 15 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 16 ) \pm ( - 16 ) ^{2} - 4 \cdot 4 \cdot 15}{2 \cdot 4}

(- 16)^{2} - 4 \cdot 4 \cdot 15 = 4

x_{1, 2} = \frac{- ( - 16 ) \pm 4}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- ( - 16 ) + 4}{2 \cdot 4}, x_{2} = \frac{- ( - 16 ) - 4}{2 \cdot 4}

x = \frac{- ( - 16 ) + 4}{2 \cdot 4} : \frac{5}{2}

x = \frac{- ( - 16 ) - 4}{2 \cdot 4} : \frac{3}{2}

The solutions to the quadratic equation are:

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

- 9 (x + 6) = - 9 x + 108

3 (y + 5) = 33

8 x^{3} - 1

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

2600 \cdot 2^{\frac{5}{2}}
