Rational Equations Quiz

What is the first step in solving rational equations as discussed in the video?

• Multiply all terms by the largest denominator

• Factor the numerators

• Find a common denominator

• Add all fractions together

Why is it important to multiply both the numerator and denominator by the same expression?

• To simplify the numerator

• To eliminate the denominator

• To maintain the fraction's value while changing its form

• To change the value of the fraction

What should you check for after solving a rational equation?

• If the solution is less than 10

• If the solution is positive

• If the solution makes any denominator zero

• If the solution is a whole number

In the second example, what is the common denominator used?

• x + 2 and x - 2

• x + 2
