Rational Equations
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A rational equation contains at least one rational expression; multiplying both sides by the LCD clears the denominators.
Show
1/x + 1/2 = 3/4: the LCD 4x turns it into 4 + 2x = 3x, a linear equation in plain clothes.
Watch for
The LCD multiplies every term on both sides.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
