Q. 2b3x−6b5xWhich of the following expressions is equivalent to the given expression for b=0 ?Choose 1 answer:(A) 6b−x(B) 3b−x(C) 2bx(D) 3b2x
Find common denominator: Find a common denominator for the two fractions.The common denominator for 2b and 6b is 6b.
Convert first fraction: Convert the first fraction to have the common denominator.(2b3x) can be written as (2b×33x×3) to have a denominator of 6b.This gives us (6b9x).
Subtract second fraction: Subtract the second fraction from the first fraction.Now we have (6b9x)−(6b5x).Since the denominators are the same, we can subtract the numerators directly.This gives us (6b9x−5x).
Perform numerator subtraction: Perform the subtraction in the numerator.9x−5x equals 4x.So, we have 6b4x.
Simplify the fraction: Simplify the fraction.(4x)/(6b) can be simplified by dividing both the numerator and the denominator by 2.This gives us (2x)/(3b).
