What is the factored form of the polynomial ? X^2-8x-9

The factors of = (x-9)(x+1).

Step-by-step explanation:

Given,

To find the factors

=

= x(x-9)+1(x-9)

= (x-9)(x+1)

The factors of = (x-9)(x+1)

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
