Solving rational equations
In this lesson, we will learn how to state the non-permissible value(s) of rational equations and how to solve them algebraically.
Basic Concepts: Solving quadratic equations by factoring
Lessons
Always find the non-permissible values before solving the rational equations as some answers might have to be rejected.
- 1.Solve the following rational equations:a)3−x3=1+x1b)2x+x15=13
- 2.Solving Rational Equations by cross multiplying
State the non-permissible values for the variable x, then solve algebraically.a)x+48=x−13b)6x−12x−2=9x+53x+4 - 3.Solve
x−92+x+920=x2−8180 - 4.Solve the following equations algebraically:a)x+22+x−23=1b)t−12t−3−t+23t+1=−1
- 5.Solving Rational Equations by factoring
State the non-permissible values for the variables, then solve algebraically.a)(x−1)x2−5x+4=−4b)x2−1x−1=2x−31
