Question

Which statement about f(x) = 12x² - 36x + 27 is true?

A The zeros are t
because f(x) = 3(2x - 3)(2x + 3).
The zeros are
because f(x) = 3(2x - 3)(2x + 3).
The only zero is
because f(x) = 3(2x - 3)².
The only zero is because f(x) = 3(2x - 3)².

Answer 1

Answer: the last one

Explanation:

factor the quadratic expression, the greatest common factor is 3, 3(4x^2-12x+9) is a perfect trinomial square. There is only one root 3/2 but it is a double
