Question 2: Factor the following polynomial completely:

am – 2a – 5m + 10

Question 3: If a ball is thrown upwards at 40 feet per second from a rooftop 24 feet above the ground, then its height above the ground t seconds after it is thrown is given by h = - 16 t2 + 40 t + 24.

a. Rewrite the above formula with the polynomial on the right hand side factored completely.

b. Use the factored version of the formula to find h when t = 3.

    1) 3ab(a+b)(a-b)

    2) a(m-2)-5(m-2) = (a-5)(m-2)

    5) 9a2b4(4ab-3+2b5)

    Um...wow..what class are you taking? Like highschool algebra? Cuz I never had to do that stuff...and I'm in Precalc...

    Umm. Question 4:

    If it only wants the extra week, I'd just plug 7 in for x and solve. Multiply 120 by (x+2). (I'm not positive, but that's what i'd do.)

    Factoring polynomials thoroughly: x^3y + 2x^2y^2 + xy^3 element out the perfect person-friendly element (GCF) = xy xy(x^2 + 2xy +y^2) element a trinomial xy(y + x) (y +x) very end result: xy(y + x) (y + x)
