- 2 x^{2} + 9 x = 4

x = \frac{1}{2}, x = 4

Decimal Notation

x = 0.5, x = 4

Solution steps

- 2 x^{2} + 9 x = 4

Move

4

to the left side

- 2 x^{2} + 9 x - 4 = 0

Solve with the quadratic formula

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

9^{2} - 4 (- 2) (- 4) = 7

x_{1, 2} = \frac{- 9 \pm 7}{2 ( - 2 )}

Separate the solutions

x_{1} = \frac{- 9 + 7}{2 ( - 2 )}, x_{2} = \frac{- 9 - 7}{2 ( - 2 )}

x = \frac{- 9 + 7}{2 ( - 2 )} : \frac{1}{2}

x = \frac{- 9 - 7}{2 ( - 2 )} : 4

The solutions to the quadratic equation are:

x = \frac{1}{2}, x = 4

x^{2} = x + x

1^{2} + x^{2} = 5^{2}

3 y^{2} - 9 y = 0

7 x^{2} + 3 x - 5 = 0

(2 x - 7 x)^{2} + 9 (2 x^{2} - 7 x) + 18 = 0
