If x – 9 is a factor of x2 – 5x – 36, what is the other factor?

x – 4
x + 4
x – 6
x + 6

Option B.

Step-by-step explanation:

The given quadratic expression is

Splitting the middle term, we get

Taking common (x-9), we get

It means (x-9) and (x+4) are two factors of given expression.

It is given that (x-9) is a factor of given expresion, so (x+4) is the other factor of given expression.

Hence, the correct option is B.

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,
