A letter to the editor is presented which discusses the method of finding the roots of the quadratic equation ax2 + bx + c = 0 by graphing y = ax2-5x, and determining the coordinates of the x-intercepts.MetzKapi'olaniJamesKapi'olaniMathematics Teacher...
Find the Zeros of the polynomial function Since the degree of the polynomial is four, we must find four Zeros, not necessarily distinct. We can factor the equation as follows : The Zeros are -3, 3, -i, and i. The two real Zeros are the x-intercepts of the function. The two imagi...
