Assume that the expression given are denomintors of fractions.find the LCD for the group

Question

k2 +5K,K2 +3k -10 is

Answer 1

k^2 +5k, k^2 +3k -10

 

k(k+5), (k+5)(k-2)

 

LCD = k(k+5)(k-2)

Answer 2

factor the polynomials

 

k^2+5k=k(k+5)

k^2+3k-10=(k+5)(k-2)

 

LCM or LCD is k(k+5)(k-2)
