x^{2} - 0.5 x - 3 = 0

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

Decimal Notation

x = 2, x = - 1.5

Solution steps

x^{2} - 0.5 x - 3 = 0

Multiply both sides by

10

10 x^{2} - 5 x - 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 5 ) \pm ( - 5 ) ^{2} - 4 \cdot 10 ( - 30 )}{2 \cdot 10}

(- 5)^{2} - 4 \cdot 10 (- 30) = 35

x_{1, 2} = \frac{- ( - 5 ) \pm 35}{2 \cdot 10}

Separate the solutions

x_{1} = \frac{- ( - 5 ) + 35}{2 \cdot 10}, x_{2} = \frac{- ( - 5 ) - 35}{2 \cdot 10}

x = \frac{- ( - 5 ) + 35}{2 \cdot 10} : 2

x = \frac{- ( - 5 ) - 35}{2 \cdot 10} : - \frac{3}{2}

The solutions to the quadratic equation are:

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

4 x^{2} - 5 x = 21

24 x^{2} + 5 x - 1 = 0

4 x^{2} - 8 = 4

a (x) = x^{2} + 7 x + 12

2 x^{2} + 48 = 0
