- 55 = - 4 x^{2} + 6 x - 1

x = - 3, x = \frac{9}{2}

Decimal Notation

x = - 3, x = 4.5

Solution steps

- 55 = - 4 x^{2} + 6 x - 1

Switch sides

- 4 x^{2} + 6 x - 1 = - 55

Move

55

to the left side

- 4 x^{2} + 6 x + 54 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 ( - 4 ) \cdot 54}{2 ( - 4 )}

6^{2} - 4 (- 4) \cdot 54 = 30

x_{1, 2} = \frac{- 6 \pm 30}{2 ( - 4 )}

Separate the solutions

x_{1} = \frac{- 6 + 30}{2 ( - 4 )}, x_{2} = \frac{- 6 - 30}{2 ( - 4 )}

x = \frac{- 6 + 30}{2 ( - 4 )} : - 3

x = \frac{- 6 - 30}{2 ( - 4 )} : \frac{9}{2}

The solutions to the quadratic equation are:

x = - 3, x = \frac{9}{2}

6 x^{2} - 2 x = 140

2 c \cdot 2 c - 2 c = 12

\frac{x ^{2}}{10} - \frac{3 x}{4} = x

25 n^{2} - 15 n + 4 = 5 n

3^{2} + x^{2} = 9^{2}
