Question
Solve each equation using completing the square. See Examples 3 and $4 .$$$x^{2}-10 x+18=0$$
Step 1
We can do this by splitting the middle term in such a way that it can be written as twice the product of the square root of the first term and some number. In this case, we can write $-10x$ as $-2*5*x$. So, the equation becomes $x^{2}-2*5*x+18=0$. Show more…
