Q. Simplify. Express your answer as a single fraction in simplest form. 35bc−b5
Identify LCM of Denominators: Identify the least common multiple (LCM) of the denominators 3 and b. Since 3 and b are not like terms and assuming b is not a multiple of 3, the LCM is 3b.
Make Denominators the Same: Make the denominators the same by multiplying the first fraction by bb and the second fraction by 33. This gives us (3⋅b)(5bc⋅b)−(b⋅3)(5⋅3).
Perform Multiplications: Perform the multiplications in the numerators and denominators. This results in (3b5b2c)−(3b15).
Combine Fractions: Combine the fractions by subtracting the numerators since the denominators are the same. The combined fraction is 3b(5b2c)−15.
Check for Simplification: Check if the numerator can be simplified further. In this case, there are no common factors between 5b2c and 15 that would allow us to simplify the fraction further, assuming c is not a multiple of 3.
