That may have been a little tricky because you haven't seen one like it before, so if you didn't feel great about it, here is a quick explanation.

Question 8
8.
Given the standard form, find the factored form.
(x-4)(x+3)
(x+4)(x-3)
(x-4)(x-3)
(x+4)(x+3)
Given the standard form, find the factored form.
(x+6)(x-7)
(x+6)(x+7)
(x-6)(x-7)
(x-6)(x+7)
Question 3
3.
Given the standard form, find the factored form.
(x-10)(x+4)
(x-5)(x+8)
(x+5)(x-8)
(x+10)(x-4)
Challenge (but you can totally figure this out): Given the standard form, find the factored form.
(a+4b)(a+8b)
(a+16b)(a+2b)
(a-4b)(a-8b)
(a-16b)(a+16b)
Analysis: Tell whether the sum (the numbers added up) of the constant terms in each factor (constant is a number without any variables) should be positive or negative when you factor the quadratic. In other words, if the factored form is (x+a)(x+b), should a+b be positive or negative?
positive
negative
Analysis: Tell whether the sum of the constant terms in each factor should be positive or negative when you factor the quadratic.
