What is the quadratic equation whose roots are 1 and -1 and whose leading coefficient is 3

(-5,-28)

i graphed to on desmos.

the answer is a.

step-by-step explanation:

in three games of golf, alex shot two under par four times.

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.
