Answer

The zeros of f(x) are 2 and 6

Explanation

The function:


f(x)=3x^2-24x+36

has the form:


f(x)=ax^2+bx+c

with the constants: a = 3, b = -24, and c = 36.

We can find the zeros of f(x) with the help of the quadratic formula, as follows:


\begin{gathered} x_(1,2)=(-b\pm√(b^2-4ac))/(2a) \\ x_(1,2)=\frac{24\pm\sqrt{(-24)^2-4\cdot3\operatorname{\cdot}36}}{2\cdot3} \\ x_(1,2)=(24\pm√(144))/(6) \\ x_1=(24+12)/(6)=6 \\ x_2=(24-12)/(6)=2 \end{gathered}
