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

- x + 3

Solution steps

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

Apply Difference of Two Squares

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

= - x + 3

x^{2} (- \frac{1}{2} x + 3)^{2}

\frac{x ( e ^{x^{2}} - 1 )}{3}

(\frac{1}{2} (x - \frac{1}{2} sin (2 x))) (cos (x))

\frac{( 2 x ^{3} - 9 x ^{2} + 3 x - 4 )}{( 2 x ^{2} - 7 x - 4 )}

(x + 3) (x - 4)
