2 c^{2} - 9 c - 2 = 0

c = \frac{9 + 97}{4}, c = \frac{9 - 97}{4}

Decimal Notation

c = 4.71221 \dots, c = - 0.21221 \dots

Solution steps

2 c^{2} - 9 c - 2 = 0

Solve with the quadratic formula

c_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 2 ( - 2 )}{2 \cdot 2}

(- 9)^{2} - 4 \cdot 2 (- 2) = 97

c_{1, 2} = \frac{- ( - 9 ) \pm 97}{2 \cdot 2}

Separate the solutions

c_{1} = \frac{- ( - 9 ) + 97}{2 \cdot 2}, c_{2} = \frac{- ( - 9 ) - 97}{2 \cdot 2}

c = \frac{- ( - 9 ) + 97}{2 \cdot 2} : \frac{9 + 97}{4}

c = \frac{- ( - 9 ) - 97}{2 \cdot 2} : \frac{9 - 97}{4}

The solutions to the quadratic equation are:

c = \frac{9 + 97}{4}, c = \frac{9 - 97}{4}

2 m^{2} - 16 m + 8 = 0

x^{2} - 10 x + 18 = x

x^{2} - x + 5 = 5

4 x^{2} + 8 x = - 7

x^{2} + 10 x - 40 = 4 x
