Find an equation of a line that passes through the point (A, B+ 1) and is perpendicular to the line Ax + By = C.
Calculate the length and the midpoint of the line segmentjoining the points (a, b) and (âa, âb).
3. Construct a quadratic equation in standard form whosesolution set is {2+ 3,2â 3}. Check that your equation has thecorrect solutions by solving it using the quadratic formula
Consider the quadratic equation ax2 + bx + c = 0. a. Show that the sum of the roots of the quadratic equation isequal to â b/a
b. Show that the product of the roots of the quadraticequation is equal to c/a
