x^2-2xy y^2

9x^2 48xy 64y^2

1-14p^4 49p^8

r^2-4x^2

36x^2-100

4x^2-9y^2

12c^2-12

y^4-x^4

r^2 11r 10

k^2-16k 15

a^2 12a-45

Update:

the first one is suposed to be p^2-2p+1

and its not home work, its a summer assignment!

    p²-2p+1 = (p-1)²

    x²-2xy+y² = (x-y)²

    9x²+48xy+64y² = (3x+8y)²

    1-14p⁴+49p^8 = 49p^8-14p^4+1 = (7p^4-1)²

    r²-4x² = (r)²-(2x)² = (r-2x)(r+2x)

    36x²-100 = 4(9x²-25) = 4(3x+5)(3x-5)

    4x²-9y² = (2x+3y)(2x-3y)

    12c²-12 = 12(c²-1) = 12(c+1)(c-1)

    y⁴-x⁴ = (y²+x²)(y²-x²)=(y²+x²)(y+x)(y-x)

    r²+11r+10 = (r+1)(r+10)

    k²-16k+15 = (k-15)(k-1)

    a²+12a-45 = (a+15)(a-3)

    Bye!

    I think you might be missing some information. For example: In the first one should there be a function (addition, multiplication, etc...) between the 2p and the 1, for the second one between the 2xy and the y^2?

    3y^(2) + 6y + 3 = 0 3( y ^(2) + 2y +1) = 0 (y+1)(y+1) =0 y= -1

    p^2-2p +1

    (p-1)(p-1)

    x^2-2xy+y^2

    (x-y)(x-y)

    the rest are all similar. Why don't you post your answers and we'll tell you if they're correct.

    Iwill assume that blank space is +

    (p-1)^2

    (x+y)^2

    (7p^4-1)^2 or (1-7p^4)^2

    (r+2x)(r-2x)

    (6x-10)(6x+10)

    (2x-3y)(2x+3y)

    12(x+1)(c-1)

    (y^2+x^2)(y+x)(y-x)

    (r-1)(r-10)

    (k-1)(k-15)

    (a-3)(a+15)
