    1) (x + 2)(x + 8)

    2) 7x^3 + 6x

    3) 20x^2

    4) (x + 4)(x + 5)

    5) (x - 5)(x - 8)

    I hope this information was very helpful.

    X^2+10x+16=

    (X+8) (x+2)

    X^2-13+40=

    Impossible

    X^2+9x+20=

    (X+4) (x+5)

    (4x)(5x) =

    20x^2

    Addition:

    This one is really simple. Just combine like terms:

    7x^3 + 6x

    Multiplication:

    Seriously?

    4*5 = 20; x*x = x^2, so 20x^2

    Factoring:

    (x+4)(x+5)

    Factoring:

    (x-5)(x-8)

    Good luck - try to learn how to solve these yourself!

    x2 + 10x + 16 = 0

    (X+8) (X+2)

    X = -8

    X = -2

    gazing this you comprehend you've got a -x and an x because of fact the 1st words. then you definately could discover factors of sixteen which will upload as much as the middle term of 6x to end this exercising. for this reason 8 and 2. (-x + 8)(x + 2) or you may change it around somewhat and positioned (8-x)(x+2)

    (x-5)(x-8)
