The quadratic formula is a formula that we use to solve quadratic equations. It states that if ax2 + bx + c = 0, then {eq}x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a} {/eq}. This formula comes in quite handy in solving quadratic equations, as the process just takes a few ...

We try the quadratic equation x2+ 21 = 10x. In order to use Proposition II-5, we rewrite this as 10x – x2= 21, or, factoring the left side, as (10 – x)x = 21. Comparing this to our formula above, we note that b = 10 and therefore we have 如此让我们看见如何使用这个等式...
