WebMay 17, 2011 · Using our general form of the quadratic, y = ax 2 + bx + c, we substitute the known values for x and y to obtain: Substituting (−2,0): 0 = a(−2) 2 + b(−2) + c = 4a − 2b + c Substituting (1,0): 0 = a(1) 2 + b(1) + c = a + b + c Substituting (0,−3): −3 = a(0) 2 + b(0) + c = c So we get c = −3. Substituting c = −3 in the first line gives: WebThe zeros of a quadratic equation are the points where the graph of the quadratic equation crosses the x-axis.
