Answer 2

Answer

( x³ + 4x² - x - 4)/( x² +3x - 4)

numerator : (x³ + 4x² - x - 4)

= x³ -x + 4x² - 4

= x(x² -1) + 4(x² -1)

= (x +4)(x² -1)

= (x + 4)(x - 1)(x + 1)

denominator : (x² + 3x - 4)

= x² + 4x - x - 4

= x(x + 4) -(x + 4)

= (x - 1)(x + 4)

now, put this in above expression.

(x +4)(x -1)(x + 1)/(x -1)(x + 4)

=(x + 1)
