Factor by grouping x3 - 3x2 + 4x -12 Group of answer choices A( x - 3 ) (x2 + 4 )
B(x3 - 3x2) ( 4x -12)
C( x +4 ) (x2 - 3 )
D( x - 4 ) (x2 + 3 )

(x² + 4)(x - 3)

or

A

Step-by-step explanation:

Step 1: Write out expression

x³ - 3x² + 4x - 12

Step 2: Factor by grouping

x³ - 3x²

x²(x - 3)

4x - 12

4(x - 3)

Step 3: Combine

(x² + 4)(x - 3)

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)
