Math Problem Statement
Divide and simplify. StartFraction 4 x Over 5 EndFraction divided by StartFraction 16 x plus 32 Over 5 x plus 10 EndFraction
Solution
We are asked to divide and simplify the expression:
Step 1: Division of Fractions
When dividing fractions, we multiply the first fraction by the reciprocal of the second. So, the division becomes:
Step 2: Factorization
Next, let's factor the expressions where possible:
- can be factored as .
- can be factored as .
Now the expression becomes:
Step 3: Cancel Common Factors
We notice that appears in both the numerator and denominator, so we can cancel this factor out. This leaves us with:
Step 4: Simplification
Now, multiply the numerators and denominators:
Finally, simplify the fraction:
Final Answer:
The simplified result is:
Would you like any further explanations or details about the process?
Here are some follow-up questions:
- What happens if the variable equals ?
- How can you apply this method to more complex algebraic fractions?
- How do you simplify a fraction when both the numerator and denominator contain polynomials?
- Why do we cancel out the common factor in the simplification step?
- What would change if the original expression involved negative signs?
Tip: Always check for common factors in both the numerator and denominator before canceling them out—it helps simplify your work!
