45 x^{2} - 78 x - 63 = 0

x = \frac{7}{3}, x = - \frac{3}{5}

Decimal Notation

x = 2.33333 \dots, x = - 0.6

Solution steps

45 x^{2} - 78 x - 63 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 78 ) \pm ( - 78 ) ^{2} - 4 \cdot 45 ( - 63 )}{2 \cdot 45}

(- 78)^{2} - 4 \cdot 45 (- 63) = 132

x_{1, 2} = \frac{- ( - 78 ) \pm 132}{2 \cdot 45}

Separate the solutions

x_{1} = \frac{- ( - 78 ) + 132}{2 \cdot 45}, x_{2} = \frac{- ( - 78 ) - 132}{2 \cdot 45}

x = \frac{- ( - 78 ) + 132}{2 \cdot 45} : \frac{7}{3}

x = \frac{- ( - 78 ) - 132}{2 \cdot 45} : - \frac{3}{5}

The solutions to the quadratic equation are:

x = \frac{7}{3}, x = - \frac{3}{5}

4 - 4 x^{2} = - 296

(u - 3)^{2} - 72 = 0

8 x^{2} = 6 x + 9

2 m^{2} + 14 = 11 m

5 x^{2} - 50 x + 120 = 0
