If you've got a quadratic equation on the form of ax2+c=0 Then you can solve the equation by using the square root of x=±√−ca Example 3x2−243=0 3x2=243 x2=2433 x2=81 x=±√81 x=9orx=−9 This method can only be used if b = 0. If we instead have an equation...
In Algebra it looks like this:x2 + bx + (b/2)2 = (x+b/2)2 "Complete the Square" So, by adding (b/2)2 we can complete the square.The result of (x+b/2)2 has x only once, which is easier to use.Keeping the BalanceNow ... we can't just add (b/2)2 without also ...
