Exercise 29 Page 40

Rewrite the given expression so that it is easier to make groups.

(3t-5)(7h-1)

Practice makes perfect

To factor by grouping, we will take the greatest common factor of the first pair of terms and the greatest common factor of the second pair of terms.

21th - 3t-35h+5

Factor out 3t

3t(7h-1) - 35h + 5

Factor out - 5

3t(7h-1)-5(7h-1)

Notice that (7h-1) is a factor of both terms, so we can factor it out.

3t(7h-1)-5(7h-1)

Factor out (7h-1)

(7h-1)(3t-5)
