if f(x)=3x^22x5, find(2u+1) can you explain how to work the problem and whats the answer
i can get to f(2u+1)=3(2u+1) after that i don't know

Best ResponseYou've already chosen the best response.0\[f(2u+1)=12u^2+8u4\] You can find the roots of u using the quadratic formula: \[u=\frac{1}{3}\pm \frac{2}{3}\rightarrow u=1, u=\frac{1}{3}\]
