f (x) = 30 - 12 x - x^{2}

= - (36 + 12 x + x^{2} - 36) + 30

= - (x + 6)^{2} + 66

What is the answer to this quadratic equation

(3 x)^{2} - 30 x - 12 = 0

https://www.quora.com/What-is-the-answer-to-this-quadratic-equation-3x-2-30x-12-0

(3 x)^{2} - 30 x - 12 = 0

(3 x)^{2} - 30 x + 25 = 37

(3 x - 5)^{2} = 37

3 x - 5 \in {37; - 37}

3 x \in {37 + 5; - 37 + 5}

x \in {\frac{3 7 + 5}{3}; \frac{- 3 7 + 5}{3}}
