網頁Introduction and Summary. This chapter deals with equations involving quadratic polynomials, i.e. polynomials of degree two. Quadratic equations are equations of the form y = ax2 + bx + c or y = a(x - h)2 + k. The shape of the graph of a quadratic equation is a parabola. The first section of this chapter explains how to graph any quadratic ... 網頁I hope these following steps help you: Now x^2 - 4x = 5 x^2 - 4x + (something) = 5 + something I want to factorise the left side of the equal sign, so I have to find a value for …
