Transcript text: We obtained that $\mathrm{p}^{\prime}(\mathrm{t})=6 \mathrm{t}^{2}-48 \mathrm{t}+90$. Find the critical points of the function $\mathrm{p}(\mathrm{t})$ by setting $\mathrm{p}^{\prime}(\mathrm{t})=0$ and solving for t . Separate multiple answers with a comma.
Solution
Solution Steps
Step 1: Set the derivative equal to zero.
We are given $p'(t) = 6t^2 - 48t + 90$. To find the critical points, we set the derivative equal to zero:
$6t^2 - 48t + 90 = 0$
Step 2: Solve for t.
Divide the equation by 6:
$t^2 - 8t + 15 = 0$
Factor the quadratic equation:
$(t - 3)(t - 5) = 0$
This gives us two solutions for t:
$t = 3$ or $t = 5$
