Divide x2-3x-10 by x plus 2?

Answer 1

(x^2 - 3x -10) / ( x + 2)

Factor

( x + 2)(x - 5) / ( x + 2)

Cancel down by 'x+2'

Hence

the answer is 'x - 5'.

Answer 2

x^2 - 3x -10 is x^2 - 5x + 2x -10 which is x(x -5) + 2(x - 5) which is (x + 2)(x - 5) and when you divide this by x + 2 the answer would be x - 5

Answer 3

x^2 - 3x - 10 = (x + 2)*(x - 5)So (x^2 - 3x - 10)/(x + 2) = x - 5
