4 x^{2} - 30 x + 56 = 0

x = 4, x = \frac{7}{2}

Solution steps

4 x^{2} - 30 x + 56 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 30 ) \pm ( - 30 ) ^{2} - 4 \cdot 4 \cdot 56}{2 \cdot 4}

(- 30)^{2} - 4 \cdot 4 \cdot 56 = 2

x_{1, 2} = \frac{- ( - 30 ) \pm 2}{2 \cdot 4}

Separate the solutions

x_{1} = \frac{- ( - 30 ) + 2}{2 \cdot 4}, x_{2} = \frac{- ( - 30 ) - 2}{2 \cdot 4}

x = \frac{- ( - 30 ) + 2}{2 \cdot 4} : 4

x = \frac{- ( - 30 ) - 2}{2 \cdot 4} : \frac{7}{2}

The solutions to the quadratic equation are:

x = 4, x = \frac{7}{2}

x^{2} + 5 x + 2

x, 7 x^{2} - 112 x + 2 y^{2} + 448 = 0

18 x^{2} - 9 x = 0

(x - 5)^{2} = - 1

6 x^{2} + 14 x + 4 = 0
