Factor:
12x2 - 21

a) (6x + 3)(2x + 7)
b) (12x + 7)(x + 3)
c) (3x + 7)(4x - 3)
d ) prime

When you factor this, the easiest way to do it is to set the expression equal to 0 and then factor out anything common to get it into a simpler form. 3 goes into both 12 and 21. . Now of course, , so that means that . We solve for x to get and and finally that . 4 is a perfect square that can be simplified, so that leaves us with . If we expand that back out we have the 2 factors as . Obviously, that is not one of your choices, so your choice is the last one: prime.

step-by-step explanation:

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
