|
Here we solve a rational equation by multiplying each of the terms in the equation by the LCD of all of the fractions. This allows us to divide to one all of the factors in the denominators and the…

Shows cross multipication of two single fractions set equat to each other to create a new equation that has no fractions and is then solvable by the typical methods.
|
|
This applies the factoring methods learned previously to solving a quadratic equation in standard form, that is with all th eterms on the left of the equals sign and 0 on the right

Demonstrates how to remove a common factor that not just a single number or variable, but a binomial i. e. a two-term expression.
|
|
Demonstrates how factor a greatest common factor (GCF) from a polynomial.
|
|
Shows how to factor the greatest common factor from a simple linear binomial
|
|
The key to getting this type of question is distributing any minus sign on the outside of the parentheses to each term on the inside thereby changing all of the i nner signs to their opposite
