For the equation
Example Question #2 :Binomial Denominators
Simplify:
In order to begin this kind of a problem, it's key to look at parts of the rational expression that can be simplified.
In this case, the denominator is an already-simplified binomial; however, the numerator can be factored through "factoring by grouping." This can be a helpful idea to keep in mind when you come across a polynomial with four terms and simplifying is involved.
This leaves two terms that are identical
Consider the denominator; the quantity
Example Question #2 :How To Find The Solution Of A Rational Equation With A Binomial Denominator
Simplify:
In order to begin this kind of a problem, it's key to look at parts of the rational expression that can be simplified.
In this case, the denominator is an already-simplified binomial; however, the numerator can be factored.
The roots will be numbers that sum up to
The options include:
When these options are summed up:
We can negate the last three options because the first option of
Because the quantity
