This question is WORTH 15 POINTS
the expression 3x² - 33x - 180 can be factored into the form a(x + b)(x + c), where a, b, and c are constants, to reveal the zeros of the function defined by the expression. What are the zeros of the function defined by 3x² - 33x - 180?

Select all that apply.

a. -15
b. -10
c. -6
d. -4
e. 4
f. 6
g. 10
h. 15


Sagot :

3x² - 33x - 180 = 0
3(x² - 11x - 60) = 0
3(x² - 15x + 4x - 60) = 0
3(x + 4)(x - 15) = 0
3(x - 4) = 0 or x - 15 = 0
3x - 12 = 0       + 15  + 15
    + 12 + 12           x = 15
       3x = 12
        3      4
         x = 3

The answer is equal to H.15 and E. 4.
