Question

Which shows the factored form of x2-12x-45

Answer 1

x^2 - 12x - 45
= (x - 15) (x + 3) .........factored form

Answer 2

`(x+3)(x-15)` is the required factorized form of the given expression.

Explanation:

The given equation is:

`x^2-12x-45`, we have to factorized this equation,

Upon solving the above equation, we get

⇒
`x^2-15x+3x-45`

⇒
`x(x-15)+3(x-15)`

⇒
`(x+3)(x-15)`

which is the required factorized form of the given expression.
