Answer:
[See Below]
Step-by-step explanation:
✦ Turn fractions into decimals:
- (We will do something different for
and
.)
✦ Divide:
- (Since the denominators are multiplies of each other we can divide them without having to change them into decimals.)
✦ Simplified Equation:
✦ Add:
✦ Subtract:
- (Subtraction rule is if there is 2 negatives next to each other in a problem it turns into a positive.)
✦ So your answer would be:
(Exact Form)
(Mixed Number Form)
(Decimal Form)

Answer:
Step-by-step explanation:
Let:
This is and exact equation, because:
So, define f(x,y) such that:
The solution will be given by:
Where C1 is an arbitrary constant
Integrate with respect to x in order to find f(x,y):
Where g(y) is an arbitrary function of y.
Differentiate f(x,y) with respect to y in order to find g(y):
Substitute into
Integrate with respect to y:
Substitute g(y) into f(x,y):
The solution is f(x,y)=C1
Solving y using quadratic formula:
