Then, $x=\alpha$ & $x=\beta$ will be the roots of the quadratic equation. We discuss factorization with an example below. Let, our quadratic equation is $x^2-5x+6=0$, now we will try to find a $\alpha$ such that $\alpha^2-5\alpha+6=0$. See, it holds true if $\alpha=...
Write an equation for the quadratic with x-intercepts (−3,0) and (2,0) and y-intercept (0,−3). Parabola Equations: Parabola equations can also be referred to as quadratic functions. One form of this equation is as follows: y=a(x−p)(x−q) In thi...
