What would be the factors if you were to solve the equation 3x^2+6x=0 by factoring?

Idon’t understand this.. will someone ? will mark brainliest along with 20 points.

Let the closed interval [a , b] be the domain of function f. the domain of f(x - 3) is given by (a) the open interval (a , b) (b) the closed interval [a , b] (c) the closed interval [a - 3 , b - 3] (d) the closed interval [a + 3 , b + 3]

Rewrite the following quadratic functions in intercept or factored form. show your work. f(t) = 20t^2 + 14t - 12
