Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12

f(x) = 3(x+2)(x-2)

Step-by-step explanation:

We are given a quadratic function and we have to write it in factored form

f(x) = 3x² - 12

we can take 3 common above

f(x) = 3 ( x² - 4 )

f(x) = 3( x² - 2²)

using formula (a²-b²) = (a+b)(a-b)

f(x) = 3(x+2)(x-2)
