(x + 1 + 2) (x + 1 - 2)

Apply Difference of Two Squares

(x + 1 + 2) (x + 1 - 2) : x - 3

= x - 3

\frac{d}{d x} ((z) (2 x y z - e^{z}))

e x p an d (- \frac{b}{a} y - \frac{c}{a} z + d)^{2} + y^{2} - z^{2}

e x p an d 5 (3 b^{2} + 4 b - 6)^{2}

e x p an d (sin (x) - 3) (sin (x) + 1)

e x p an d \frac{y ( x ^{2} + y ^{2} ) ^{2}}{x ^{5}}
