Question

its like multiplying fractions but just with polynomials please help me

 

(a²+2a+1)/(a+1) •( a²-1)/(a-1)

Answer 1

You're right, it is like multiplying fractions but just with polynomials.  So you can apply the same techniques you use when multiplying fractions. For example, if a were equal to 5, then your expression would be equal to  

 

(36/6) * (24/4)  

 

which you could factor to get  

 

(6*6/6) * (6*4/4)  

 

which reduces to  

 

6*6 = 36  

 

Use the same factoring process but just with polynomials instead of numeric values
