(2x3 + 7x2 + x) + 2(x2 - 2x - 6) splifly

2x³ + 3(3x - 4)(x + 1)

Step-by-step explanation:

(2x³ + 7x² + x) + 2(x² - 2x - 6)

2x³ + 7x² + x + 2x² - 4x - 12

2x³ + 9x² - 3x - 12

2x³ + 3(3x² - x - 4)

2x³ +3(3x - 4)(3x + 3)/3

2x³ + (3x - 4)(3x + 3)

2x³ + 3(3x - 4)(x + 1)

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)
