x, - 4 x^{2} - 42 x + 22 = 0

x = - 11, x = \frac{1}{2}

Decimal Notation

x = - 11, x = 0.5

Solution steps

- 4 x^{2} - 42 x + 22 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 42 ) \pm ( - 42 ) ^{2} - 4 ( - 4 ) \cdot 22}{2 ( - 4 )}

(- 42)^{2} - 4 (- 4) \cdot 22 = 46

x_{1, 2} = \frac{- ( - 42 ) \pm 46}{2 ( - 4 )}

Separate the solutions

x_{1} = \frac{- ( - 42 ) + 46}{2 ( - 4 )}, x_{2} = \frac{- ( - 42 ) - 46}{2 ( - 4 )}

x = \frac{- ( - 42 ) + 46}{2 ( - 4 )} : - 11

x = \frac{- ( - 42 ) - 46}{2 ( - 4 )} : \frac{1}{2}

The solutions to the quadratic equation are:

x = - 11, x = \frac{1}{2}

20 x^{2} - 2 x - 14 = 0

x^{2} - 10 + 16 = 0

x^{2} - x + 0.21 = 0

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

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