4 X^{2} - 5 X - 6 = 0

X = 2, X = - \frac{3}{4}

Decimal Notation

X = 2, X = - 0.75

Solution steps

4 X^{2} - 5 X - 6 = 0

Solve with the quadratic formula

X_{1, 2} = \frac{- ( - 5 ) \pm ( - 5 ) ^{2} - 4 \cdot 4 ( - 6 )}{2 \cdot 4}

(- 5)^{2} - 4 \cdot 4 (- 6) = 11

X_{1, 2} = \frac{- ( - 5 ) \pm 11}{2 \cdot 4}

Separate the solutions

X_{1} = \frac{- ( - 5 ) + 11}{2 \cdot 4}, X_{2} = \frac{- ( - 5 ) - 11}{2 \cdot 4}

X = \frac{- ( - 5 ) + 11}{2 \cdot 4} : 2

X = \frac{- ( - 5 ) - 11}{2 \cdot 4} : - \frac{3}{4}

The solutions to the quadratic equation are:

X = 2, X = - \frac{3}{4}

6 x^{2} - 67 x - 100 = 0

x^{2} - 5 x + (- 25) = 4

\frac{- 11.86666 x ^{2} + 379.0771 x - 2604.10485}{2} = 0

1 + 6 x = 4 x^{2}

x, x^{2} + 8 x + y^{2} - 4 y + z^{2} - 6 z + 20 = 0
