Question

-18+11x-x^2
Step by step explanation plzzz.....Quickly

Answer 1

$- 18 + 11x - {x}^{2} \\ rearranging \: the \: equation \\ - {x}^{2} + 11x - 18 \\ = > { x}^{2} - 11 + 18 \\ = > {x}^{2} - 9x - 2x + 18 \\ = > x(x - 9) - 2(x - 9) \\ = > (x - 9)(x - 2)$

Answer 2

Answer:

-2&-9

Step-by-step explanation:

-18+11x-x^2 can be write as

$- x {}^{2} + 11x - 18$

to fractrize we write it as

$- x {}^{2} - 9x - 2x - 18 \\ - x(x + 9) - 2(x + 9) \\ (x + 9)( - x - 2) \\ x + 9 = 0 \\ x = - 9 \\ and\\ - x - 2 = 0 \\ - x = 2 \\ x = - 2 \\ the \: roots \: are \: - 9 \: and \: - 2$
