Part 2) The solutions are
and
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
The discriminant is equal to

If D=0 -----> the quadratic equation has only one real solution
If D>0 -----> the quadratic equation has two real solutions
If D<0 -----> the quadratic equation has two complex solutions
<em>Find the value of D</em>
-----> the quadratic equation has two complex solutions
<em>Find out the solutions</em>
substitute the values of a,b and c in the formula
Remember that

Answer:
Step-by-step explanation:
<u>Let's use PRT/100 to see what will be the total amount.</u>
- Total amount = Interest + Principle
<u>Solution:</u>
- PRT/100 = Interest
- => 2000 x 3.75 x 20 years/100
- => 20 x 3.75 x 20 = Interest
- => 2 x 2 x 375 = Interest
- => 4 x 375 = Interest
- => 1500 = Interest
- => Total amount = 1500 + 2000
- => Total amount = $3500
Hence, after 20 years, the amount earned is $3500.
