    Factoring Polynomials
    1) Determine the GCF of each pair. (1 mark each)

    a) 4a, 6a
    b) 12m3, 10m2
    c) 9mn2, 8mn
    d) 15bc, 25b2c

    2) Determine the GCF of each set. (1 mark each)

    a) 5xyz, 10abc, 25pqr
    b) 20x, 10x3, 8x2
    c) 12abc, 18ab, 6ac
    d) 10x2y, 15xy2, 25xyz

    3) State the missing factor. (The question mark is the missing factor) (1 mark each)

    a) 12x + 18y = ( ? )(2x + 3y)
    b) 3x2 5x = ( ? ) (3x 5)
    c) 3y2 + 18y = 3y(y + ?)
    d) 4a3 8a2 = 4a2 (? - 2)
    e) 14a 12b = 2(? - 6b)

    4. Factor each of the following. (1 mark each)

    a) 10x + 15
    b) 2mn n
    c) 8x2 + 4x3
    d) 4a 8b + 16
    e) 12x3 6x2 + 24x
    f) 10x3 5x2 + 15x
    g) 24x4y 18x3y + 12x2y2

    1) Determine the GCF of each pair. (1 mark each)

    a) 4a, 6a = 2a
    b) 12m3, 10m2 = 10m^2
    c) 9mn2, 8mn = 6mn
    d) 15bc, 25b2c = 5bc

    I think those all right, but not sure.
    I find the common factor between them then use that number then find the common variables.

    2) Determine the GCF of each set. (1 mark each)

    a) 5xyz, 10abc, 25pqr = 5.. I'm really confused on the variables part.
    b) 20x, 10x3, 8x2 =
    c) 12abc, 18ab, 6ac =
    d) 10x2y, 15xy2, 25xyz = 5

    These I don't understand at all. (the 2's or 3's that are in between or next to variables are meant to be exponents. They just don't show as they are supposed to"

    3) State the missing factor. (The question mark is the missing factor) (1 mark each)

    a) 12x + 18y = ( ? )(2x + 3y) = 6x
    b) 3x2 5x = ( ? ) (3x 5) = 1x
    c) 3y2 + 18y = 3y(y + ?)
    d) 4a3 8a2 = 4a2 (? - 2)
    e) 14a 12b = 2(? - 6b)

    So on these this is what I'd do:
    a)
    6,x
    6,y
    6x(2x + 3y)
    6x(2x) + 6x(3y)
    12x + 18y

    Im dull when it comes to math.
