find all holes of the following function. if a hole exists, write your answer as a coordinate point in simplest form.
\\( f(x) = \frac{5x^2 + 33x - 56}{3x^2 + 3x} \\)
Step1: Factor numerator and denominator
First, factor the numerator \(5x^{2}+33x - 56\). We need two numbers that multiply to \(5\times(-56)=-280\) and add to \(33\). The numbers are \(40\) and \(-7\). So,
Next, factor the denominator \(3x^{2}+3x = 3x(x + 1)\).
Step2: Identify common factors
For a rational function, a hole occurs when there is a common factor in the numerator and the denominator. Here, the numerator is \((5x - 7)(x + 8)\) and the denominator is \(3x(x + 1)\). There are no common factors between the numerator and the denominator.
