4 x^{2} + 6 x - 86 = 2

x = 4, x = - \frac{11}{2}

Decimal

x = 4, x = - 5.5

Solution steps

4 x^{2} + 6 x - 86 = 2

Move

2

to the left side

4 x^{2} + 6 x - 88 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 4 ( - 88 )}{2 \cdot 4}

6^{2} - 4 \cdot 4 (- 88) = 38

x_{1, 2} = \frac{- 6 \pm 38}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- 6 + 38}{2 \cdot 4}, x_{2} = \frac{- 6 - 38}{2 \cdot 4}

x = \frac{- 6 + 38}{2 \cdot 4} : 4

x = \frac{- 6 - 38}{2 \cdot 4} : - \frac{11}{2}

The solutions to the quadratic equation are:

x = 4, x = - \frac{11}{2}

3 x^{2} + (- 6 x) + 14 - 2 x^{2} + (- 18) + 7 x = 2 x - 4

3 r^{2} + 27 r = 12

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

18 x^{2} - 9 x - 5 = 0

4 n^{2} + 8 n + 4 = 0
