2.Find the product:(2x-4y)(2x+4y)

4.Find the product:(8x-3y)^2
d.64x^2-48xy-9y^2 (b)

  • Math -

    (x^2 -2)(x^3 - 4x + 9)

    (x^2) (x^3) = x^5

    (x^2) (-4x) = -4x^3

    (x^2) (9) = 9x^2

    (-2) (x^3) = -2x^3

    (-2) (-4x) = 8x

    (-2) (9) = 18

    Now, we add the right-hand sides of the equeal sign.

    x^5 - 4x^3 - 2x^3 + 9x^2 + 8x - 18

    x^5 - 6x^3 + 9x^2 + 8x - 18

    There I did the 1st one for u. Try and do the rest.

  • Math -


    4x^2 + 8xy - 8xy - 16y^2

    4x^2 - 16y2

  • Math -


    (8x - 3y) (8x - 3y)

    Try finish it from there...
