Question

Find the zeroes of the function f(x).
f(x)=(x–3)(x+4)

Answer 1

Answer:Set \displaystyle f\left(x\right)=0f(x)=0.

Explanation:

Set \displaystyle f\left(x\right)=0f(x)=0.

If the polynomial function is not given in factored form:

Factor out any common monomial factors.

Factor any factorable binomials or trinomials.

Set each factor equal to zero and solve to find the \displaystyle x\text{-}x- intercepts.
