Q. Perform the following operation and express in simplest form.6xx2−2x−48⋅x2−36x−6Answer:
Factor Numerator and Denominator: Factor the numerator and the denominator where possible.The numerator x2−2x−48 can be factored into (x−8)(x+6).The denominator x2−36 can be factored into (x−6)(x+6) because it is a difference of squares.
Write with Factored Terms: Write the expression with the factored terms.The expression now looks like this:((x−8)(x+6))/(6x)⋅(x−6)/((x−6)(x+6))
Cancel Common Terms: Cancel out the common terms.The (x+6) terms cancel out, as do the (x−6) terms, as long as x is not equal to −6 or 6 (since division by zero is undefined).The expression simplifies to:6xx−8
Check for Further Simplification: Check for any further simplification. There are no common factors between the numerator (x−8) and the denominator 6x, so the expression is already in its simplest form.
