\(\displaystyle y = 3x^{3} + 2x^{2} + x + 5\)
Basically you have to factor the cube and the square. That's the challenge. But I can do the square.
Book answers (How did it get there?)
\(\displaystyle 9x^{2} + 4x + 1\)
\(\displaystyle x = 3\)
\(\displaystyle y = 94\) = slope of the tangent line at \(\displaystyle x = 3\)
