When the quadratic expression is x^2 +ax + ..., the binomial square will be
.. (x +(a/2)^2
You have a=-2, so the binomial square will be of the form (x -1)^2. You don't even need to work out the rest of it to know that ...
.. the 4th selection is appropriate.
Answer:
Victor's equation did not correctly model the problem.
The equation that correctly modeled the problem:
$129.85-$89.25=$40.60
Step-by-step explanation:
The amount required for bicycle purchase by Victor is $129.85 out of which $89.25 has been saved,in other words,the balance required for Victor to reach his target purchase price is the difference between the total cost of $129.85 and the $89.25 already saved.
The balance required=$129.85-$89.25=$40.6
This shows that the equation put forward by Victor is wrong.
An equation that correctly represents the problem is the difference between the target savings and the amount already saved as stated above
