Q. Perform the operation and express your answer as a single fraction in simplest form.5x21−6xAnswer:
Identify Given Expression: Identify the given expression and the operation to be performed.We are given the expression (1)/(5x2)−6x and we need to simplify it.
Recognize Type of Problem: Recognize that the expression is not a fraction subtraction problem but rather a polynomial with a fraction and a whole term.We need to find a common denominator to combine the terms into a single fraction.
Determine Least Common Denominator: Determine the least common denominator (LCD) for the terms.The LCD for 5x2 and 1 (considering the term −6x as −6x/1) is 5x2.
Rewrite Terms with LCD: Rewrite each term with the common denominator.The first term is already over the common denominator, so it remains (5x21). The second term, −6x, needs to be written with the common denominator, which gives us (5x2−6x⋅5x2).
Perform Multiplication: Perform the multiplication in the second term.Multiplying −6x by 5x2 gives us −30x3. So now we have (1)/(5x2)−(−30x3)/(5x2).
Combine Terms Over LCD: Combine the terms over the common denominator.Now we can combine the terms to get a single fraction: (1−(−30x3))/(5x2).
Simplify Numerator: Simplify the numerator by adding the opposite.The numerator simplifies to 1+30x3, so the fraction becomes (1+30x3)/(5x2).
Check Further Simplification: Check if the fraction can be simplified further.The fraction (1+30x3)/(5x2) cannot be simplified further because the numerator and denominator do not have common factors other than 1.
