Question 1018025: 3. Factor each of the following expressions.
a. x2 + 14x + 49
Answer:
b. 81w2 – 36wz + 4z2
Answer:
4.Mila factored m2 + 12mn + 144n2 as shown.
I know that since and , the first and third terms of the trinomial are perfect squares. This means that m2 + 12mn + 144n2 = (m + 12)2.

3.	Factor each of the following expressions.
		a.   x2 + 14x + 49
				Answer:  %28x%2B7%29%5E2
	b.	81w2 – 36wz + 4z2
				Answer:  %289w-2z%29%5E2

4.Mila factored m2 + 12mn + 144n2 as shown.
I know that since   and  , the first and third terms of the trinomial are perfect squares. This means that m2 + 12mn + 144n2 = (m + 12)2.
	
Comment of Mila’s strategy.  This written "strategy" is only a necessary condition, but it is not sufficient. You should look in the middle term too.
		Answer:  m%5E2+%2B+12mn+%2B+144n%5E2 =/= %28m+%2B+12%29%5E2

Answer:
Comment on Mila's answer: Factoring m%5E2+%2B+12mn+%2B+144n%5E2 DOES NOT result in %28m+%2B+12%29%5E2
