Question
Simplify each expression. Each exercise contains a four-term polynomial that should be factored by grouping.$$\frac{5 x+15-x y-3 y}{2 x+6}$$
Step 1
In the numerator, we can factor out 5 from the first two terms and -1 from the last two terms. In the denominator, we can factor out 2. This gives us: $$ \frac{5(x+3)-y(x+3)}{2(x+3)} $$ Show more…

Simplify each expression. Each exercise contains a four-term polynomial that should be factored by grouping. $$ \frac{2 x y+2 x-3 y-3}{2 x y+4 x-3 y-6} $$
Factor each four-term polynomial by grouping. If this is not possible, write "not factorable by grouping." $$ 5 x y-15 x-6 y+18 $$
