The first one has the common denominator of x, so just subtract the numerators : )
2. needs a common denominator. To make the common denominator of c^2 you must multiply the numerator and denominator of the first fraction by c thus
= 6c/c^2 + 4/c^2
= (6c + 4)/c^2
you could factor out of the top, but it wouldn't change the rational expression : )
3. Factor both denominators and find your common denominator, then continue : )
4. YIPPEEEE! Long division (or synthetic division) your choice : )
1. Simplify the expression
4 3
— - —
x x
2. Simplify the expression
6 4
— + —
c c²
3. Simplify the expression
3y 9y
— ÷ —
4y - 8 2y² - 4y
4. Simplify the expression:
( 2x³ - x² - 13x - 6 ) ÷ ( x -3 )
