6 x^{2} + 45 x + 21 = 0

x = - \frac{1}{2}, x = - 7

Decimal Notation

x = - 0.5, x = - 7

Solution steps

6 x^{2} + 45 x + 21 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 45 \pm 4 5 ^{2} - 4 \cdot 6 \cdot 21}{2 \cdot 6}

4 5^{2} - 4 \cdot 6 \cdot 21 = 39

x_{1, 2} = \frac{- 45 \pm 39}{2 \cdot 6}

Separate the solutions

x_{1} = \frac{- 45 + 39}{2 \cdot 6}, x_{2} = \frac{- 45 - 39}{2 \cdot 6}

x = \frac{- 45 + 39}{2 \cdot 6} : - \frac{1}{2}

x = \frac{- 45 - 39}{2 \cdot 6} : - 7

The solutions to the quadratic equation are:

x = - \frac{1}{2}, x = - 7

x^{2} + 12 x + c

- x (- 6 (x) + 1) = 1

2 a^{2} + 4 a - 6 = - 3 a

y, 2 x^{2} - x y + y^{2} = 16

y, x^{2} = \frac{1}{y} - 1
