- 11 x + 5 + 2 x^{2} = 0

x = 5, x = \frac{1}{2}

Decimal Notation

x = 5, x = 0.5

Solution steps

- 11 x + 5 + 2 x^{2} = 0

Write in the standard form

a x^{2} + b x + c = 0

2 x^{2} - 11 x + 5 = 0

Solve with the quadratic formula

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

(- 11)^{2} - 4 \cdot 2 \cdot 5 = 9

x_{1, 2} = \frac{- ( - 11 ) \pm 9}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- ( - 11 ) + 9}{2 \cdot 2}, x_{2} = \frac{- ( - 11 ) - 9}{2 \cdot 2}

x = \frac{- ( - 11 ) + 9}{2 \cdot 2} : 5

x = \frac{- ( - 11 ) - 9}{2 \cdot 2} : \frac{1}{2}

The solutions to the quadratic equation are:

x = 5, x = \frac{1}{2}

7 - 4 (y + 3) - (y + 3)^{2} = 0

2 x^{2} - 7 x - 3 = 0

p^{2} - 10 = 3 p

- 3 x^{2} + 9 x - 2 = 0

- 4 x^{2} + 3 = 5 x^{2} - 6 x - 4
