A landscaper is designing a flower garden in the shape of a trapezoid. She wants the shorter base to be 3 yards greater than the height and the longer base to be 7 yards greater than the height. She wants the area to be 295 square yards. The situation is modeled by the equation h2 + 5h = 295. Use the Quadratic Formula to find the height that will give the desired area. Round to the nearest hundredth of a yard.

can someone help me please

so, what is confusing about using the quadratic formula?

h^2 + 5h - 295 = 0

h = (-5±√(5^2 + 4*295)]/2

not so bad, eh?
