2 x^{2} + 3 x - 16 = 4

x = \frac{5}{2}, x = - 4

Solution steps

2 x^{2} + 3 x - 16 = 4

Move

4

to the left side

2 x^{2} + 3 x - 20 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 \cdot 2 ( - 20 )}{2 \cdot 2}

3^{2} - 4 \cdot 2 (- 20) = 13

x_{1, 2} = \frac{- 3 \pm 13}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- 3 + 13}{2 \cdot 2}, x_{2} = \frac{- 3 - 13}{2 \cdot 2}

x = \frac{- 3 + 13}{2 \cdot 2} : \frac{5}{2}

x = \frac{- 3 - 13}{2 \cdot 2} : - 4

The solutions to the quadratic equation are:

x = \frac{5}{2}, x = - 4

v^{2} = 47

6 x^{2} = - x + 1

(x - 1)^{2} + 3 = 2 x + 1

64 = 80 t - 16 t^{2}

2 x^{2} + x = - 9
