- 12 X^{2} + 30 X + 18 = 0

X = - \frac{1}{2}, X = 3

Decimal

X = - 0.5, X = 3

Solution steps

- 12 X^{2} + 30 X + 18 = 0

Solve with the quadratic formula

X_{1, 2} = \frac{- 30 \pm 3 0 ^{2} - 4 ( - 12 ) \cdot 18}{2 ( - 12 )}

3 0^{2} - 4 (- 12) \cdot 18 = 42

X_{1, 2} = \frac{- 30 \pm 42}{2 ( - 12 )}

Separate the solutions

X_{1} = \frac{- 30 + 42}{2 ( - 12 )}, X_{2} = \frac{- 30 - 42}{2 ( - 12 )}

X = \frac{- 30 + 42}{2 ( - 12 )} : - \frac{1}{2}

X = \frac{- 30 - 42}{2 ( - 12 )} : 3

The solutions to the quadratic equation are:

X = - \frac{1}{2}, X = 3

A, A = \frac{1}{2} π r^{2}

10 x^{2} - 4 x + 1 = 6 x^{2}

16 x^{2} = 96 x - 150

8 z^{2} + 18 z - 7 = - 2

x^{2} + 2 x - 8 = 0
