Question

factorise x3
+ x2 - 17x+15​

Answer 1

Answer:

x³ - x²  - 17x - 15  = (x + 1)(x + 3)(x - 5)

Step-by-step explanation:

plz mark as brainliest answer plz yaar help and thx for the brilliant question

x³ - x²  - 17x - 15

= (x + 1)(x² - 2x  - 15)

= (x + 1)(x² - 5x + 3x - 15)

= (x + 1)(x(x - 5) + 3(x - 5))

=(x + 1)(x + 3)(x - 5)

x³ - x²  - 17x - 15  = (x + 1)(x + 3)(x - 5)
