3 x^{2} - 30 x + 63 = 0

x = 7, x = 3

Solution steps

3 x^{2} - 30 x + 63 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 30 ) \pm ( - 30 ) ^{2} - 4 \cdot 3 \cdot 63}{2 \cdot 3}

(- 30)^{2} - 4 \cdot 3 \cdot 63 = 12

x_{1, 2} = \frac{- ( - 30 ) \pm 12}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 30 ) + 12}{2 \cdot 3}, x_{2} = \frac{- ( - 30 ) - 12}{2 \cdot 3}

x = \frac{- ( - 30 ) + 12}{2 \cdot 3} : 7

x = \frac{- ( - 30 ) - 12}{2 \cdot 3} : 3

The solutions to the quadratic equation are:

x = 7, x = 3

x^{2} - 18 x = - 66

x^{2} + \frac{1}{2} x + 3

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

4 (x^{2} - 4) - 5 (3 + 2 x) = - 7

(x - 7) (x + 4) = 0
