Question

If 1-9x is one of the factors of the expression 1-5x-36x2 then find the another factor of it.​

Answer 1

Answer:

x+4

Step-by-step explanation:

⇒ x2 + 4x - 9x – 36

⇒ x (x + 4) - 9 (x + 4)

⇒ (x + 4) (x - 9)

Hence, the factors that satisfy the polynomial x2 – 5x – 36 are (x + 4) and (x - 9).

Thus the other factor is (x + 4)
