Four students are verifying that x2 + x– 12 = (x – 3)(x + 4). their conclusions are presented in the table. which student correctly verified that x2 + x – 12 = (x – 3)(x + 4)? damien lauryn rico latisha

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
