Using the function \(f(x) = x^2 + x\) for each step, evaluate and simplify the following expressions (where \(h \neq 0\)). Make sure to combine like terms and simplify when possible.\(f(1+h) =\) \(f(1+h) – f(1) =\) \(\displaystyle \lim_{h \to 0} \frac{f(1+h) – f(1)}{h} =\) Equation of the tangent line to \(f(x)\) at the point \((1, 2)\):
