Question

Factorize the polynomials
x²-8x-9​

Answer 1

Answer:

factorizing x²-8x-9 , we get  (x-9)(x+1)

Step-by-step explanation:

we need to Factorize the polynomials   x²-8x-9​

it can be written as :

$x^2-9x+x-9$

let's take 'x' common from (x²-9x) from above equation

⇒ x(x-9) +(x-9)

now take (x-9) from above equation

⇒ $x(x-9) + 1 (x-9)$

it is (x-9)(x+1)

hence x²-8x-9​ can be written as (x-9)(x+1)

factorizing x²-8x-9 , we get  (x-9)(x+1)

Answer 2

Answer:

Solution :-

✪ x² - 8x - 9

➩ x² - (9 - 1)x - 9

➩ x² - 9x + x - 9

➩ x(x - 9) + 1(x - 9)

➩ (x - 9) (x + 1)

∴ The answer of this question is (x - 9) (x + 1)
