<u>Simplify both sides of the equation</u>
<u></u>![x+1.2x+1=100](https://tex.z-dn.net/?f=x%2B1.2x%2B1%3D100)
(Combine Like Terms)
![2.2x+1=100](https://tex.z-dn.net/?f=2.2x%2B1%3D100)
<u>Subtract 1 from both sides</u>

Let d=discriminant. The the rule is:
d>0, there are two real solutions
d=0, there is one real solution
d<0, there is no real solutions (but there are two imaginary solutions)
So if it is positive, there are two real solutions.

Answer:
principal, or amount your account starts with. This could be a starting investment, or the starting amount of a loan. Interest, in its most simple form, is calculated as a percent of the principal. For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5. The total amount you would repay would be $105, the original principal plus the interest.
