How to solve a rational equation as a proportion

What is the first step in factoring the expression X - 1 * X + 1?

• Factor each term separately

• Multiply the terms directly

• Identify the LCD

• Add the terms together

When simplifying the expression X - 2 * X - 2 * X + 1, what should you do after identifying the LCD?

• Multiply all terms

• Add all terms

• Cancel out common terms

• Divide by the LCD

In the process of simplifying expressions, which terms are typically canceled out?

• Terms that are subtracted

• Terms that are multiplied by zero

• Terms that are identical in numerator and denominator

• Terms that are added together

What is an alternative method to solve equations besides using the LCD?

• Using substitution

• Graphing the equation

• Applying the cross product

• Using the quadratic formula

Why might the cross product method be considered easier in some cases?

• It requires fewer steps

• It uses addition instead of multiplication

• It simplifies the equation directly

• It avoids factoring
