- 7 k^{2} + 63 k = 0

k = 0, k = 9

Solution steps

- 7 k^{2} + 63 k = 0

Solve with the quadratic formula

k_{1, 2} = \frac{- 63 \pm 6 3 ^{2} - 4 ( - 7 ) \cdot 0}{2 ( - 7 )}

6 3^{2} - 4 (- 7) \cdot 0 = 63

k_{1, 2} = \frac{- 63 \pm 63}{2 ( - 7 )}

Separate the solutions

k_{1} = \frac{- 63 + 63}{2 ( - 7 )}, k_{2} = \frac{- 63 - 63}{2 ( - 7 )}

k = \frac{- 63 + 63}{2 ( - 7 )} : 0

k = \frac{- 63 - 63}{2 ( - 7 )} : 9

The solutions to the quadratic equation are:

k = 0, k = 9

5 r^{2} - 12 r + 2 = - 3 r

2 p^{2} - 6 p - 56 = 0

(4 y + 12)^{2} = 32

6 x^{2} - 6 x + 9 = 0

x^{2} - 2 x + 1 - 2 = 0
