Which shows one way to determine the factors of x3 + 11x2 – 3x – 33 by grouping?
a. x2(x + 11) + 3(x – 11)
b. x2(x – 11) – 3(x – 11)
c. x2(x + 11) + 3(x + 11)
d. x2(x + 11) – 3(x + 11)

For this case we have the following polynomial:

We group the terms of the expression. For this, we make use of parentheses.

We have then:

For the first parenthesis, we do factor x ^ 2.

For the second parenthesis, we make factor conmun equal to 3.

We have then:

way to determine the factors by grouping is:

option D

greater than one

step-by-step explanation:

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
