Answer 1

Answer:

SOLUTION

Let the other polynomial be f(x),

As we know,

Product of two numbers = Product of their LCM & HCF

⇒ (x2 - 4x - 21) × f(x) = (x + 3)(x3 - 9x2 - x + 105)

⇒ (x + 3)(x - 7) × f(x) = (x + 3)(x3 - 9x2 - x + 105)

⇒ f(x) = (x3 - 9x2 - x + 105)/(x - 7)

∴ f(x) = (x2 - 2x - 15)
