Completing the square

7/2=3.5
3.5^2=12.25
add that to both sides
x<span>²-7x+12.25+3=12.25
factor perfect square
(x-3.5)</span><span>²+3=12.25
minus 3 both sides
(x-3.5)</span><span>²=9.25
square root both sides
x-3.5=+/-√9.25
add 3.5 to both sides
x=3.5+/-√9.25

x=3.5+√9.25 or 3.5-√9.25</span>

<em>Factors and multiples are related by multiplication.</em>

<h2>Explanation:</h2>

When you multiply numbers together to find a number, say, n, then those numbers are called factors of n. For instance:

a\times b \times c=n \\ \\ \\ Where: \\ \\ a,b,c \ are\ factors \ of \ n

On the other hand, a multiple, say, n, results when multiplying a number by an integer. For instance:

n=k\times a \\ \\ With \ k \ integer

So n is multiple of a

<em></em>

<em>As you can see, both factors and multiples implies a multiplication. So factors and multiples are related by multiplication.</em>
