Your answer is:
(125 - 8x^3) / (25 + 10x + 4x^2) = - ((2x - 5) * (4x^2 + 10x + 25)) / (4x^2 + 10x + 25) = - (2x - 5) = - 2x + 5
The correct result would be - 2x + 5.
The amount in simple interest is $3624 and in compound interest is $3674 the difference is of $50. So he should choose Simple interest.
<h3>What is compound and simple interest?</h3>
Simple interest is based on the principal amount of a loan or deposit. In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period.
Here we have the principle is $3000 for 4 years at the rate of interest of 5.2%. Now we will calculate the total amount by simple interest and compounded annually.
By using Simple interest:-

So the total amount will be =3000+624=$3624
By using the Compound interest formula:



The difference between the two amounts will be =3764-3624=$50
Hence amount in simple interest is $3624 and in compound interest is $3674 the difference is of $50. So he should choose Simple interest.
