3 k^{2} - 30 k + 87 = 0

k = 5 + 2 i, k = 5 - 2 i

Solution steps

3 k^{2} - 30 k + 87 = 0

Solve with the quadratic formula

k_{1, 2} = \frac{- ( - 30 ) \pm ( - 30 ) ^{2} - 4 \cdot 3 \cdot 87}{2 \cdot 3}

Simplify

(- 30)^{2} - 4 \cdot 3 \cdot 87 : 12 i

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

Separate the solutions

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

k = \frac{- ( - 30 ) + 12 i}{2 \cdot 3} : 5 + 2 i

k = \frac{- ( - 30 ) - 12 i}{2 \cdot 3} : 5 - 2 i

The solutions to the quadratic equation are:

k = 5 + 2 i, k = 5 - 2 i

66 - x^{2} + x = 10

x^{2} + 3 x \geq - 2

x + 4 = 9

- 5 y - 7 \leq 3

12 < - 3 (x - 2) < 24
