Math Case

All of these three problems involve prime factor of some number, it is up to us on how to solve these equations.

Problem # 98 on page 345-6

3h2t + 6ht + 3t The GFC of this problem is 3t

3t x h2 +3t x 2h + 3t x 1 The trinomial is in this form of a perfect square

3t (h2`+ 2h +1) Showing the squared binomial

3t (h+1) This is the final answer written to the

appropriately squared form.

Problem # 102 page 345-6

This factoring problem will be solved by using grouping

-3 + 27 + 21y2 Here are the three terms to group

-3 + 2y + 7y2 The common factor to start grouping is 3

-3 + 1 (2y) + 7y2 The different of squared from the first group

(9y - 3)2 This would be the completed factored

Problem # 64 Page 253

3x2 - 17x +10 Factor by grouping

3x2 - 17x + 5

(14x +5)2
