Rewrite in vertex form
The vertex form of an equation is in form of: 
Solving: 
Subtract 2 from both sides


Factorize expression on the right hand side by dividing through by the coefficient of x²


Get a perfect square of coefficient of x; then add to both sides
------------------------------------------------------------------------------------
<em>Rough work</em>
The coefficient of x is 
It's square is 
Adding inside the bracket of
to give: 
To balance the equation, the same expression must be added to the other side of the equation;
Equivalent expression is: 
------------------------------------------------------------------------------------
The expression becomes



Factorize the expression on the right hand side





Make y the subject of formula

<em>Solved</em>
True, because without the preparation for retirement, there will be nowhere to store retirement funds.
Not sure if this is what you mean but this is what I got.
Okay, move the decimal behind the 8. There are 4 places before the decimal so it is nagitive. If there are places Infront of the decimal is nagitive. So the answer is 8.235×10-4
16: 14 - divide by 2
16/2= 8 , 14/2=7
64:60- divide by 4
64/4= 16 , 60/4= 15
Answer: 16:14 and 64:60 are not equivalent.
