Question

18. Without actual division, show that (x-3x - 13x +15) is exactly
divisible by (x2 + 2x - 3).​

Answer 1

Answer:

(x²-3x-13x+15)/(x²+2x-3)

x²-16x+15/x²+2x-3

x²-15x-x+15/x²+3x-x-3

x(x-15)-1(x-15)/x(x+3)-1(x+3)

(x-1)(x-15)/x+3)(x-1)

x-15/x+3

x=15/x= - 3

15/-3

= - 5

Therefore, we can say this is exactly divisible by this. For Quotient = - 5
