MathJax v3 Dynamic Equations Using CSS and JavaScript

Expand the following: $\begin{aligned} (x + 1)^{2} & = (x + 1) (x + 1) \\ = x (x + 1) + 1 (x + 1) \\ = (x^{2} + x) + (x + 1) \\ = x^{2} + (x + x) + 1 \\ = x^{2} + 2 x + 1 \end{aligned}$

Solve for $x$ in the equation: $\begin{aligned} 2 x + 5 & = 15 \\ 2 x = 15 - 5 \\ 2 x = 10 \\ x = 5 \end{aligned}$

Find the derivative of: $\begin{aligned} f (x) & = x^{3} - 4 x^{2} + 6 x - 2 \\ f^{'} (x) = 3 x^{2} - 8 x + 6 \end{aligned}$

Compute the integral: $\begin{aligned} \int (3 x^{2} - 8 x + 6) d x \\ = \frac{3}{3} x^{3} - \frac{8}{2} x^{2} + 6 x + C \\ = x^{3} - 4 x^{2} + 6 x + C \end{aligned}$
