2. 100y^2 - 4x^2 = ( 10y - 2x)(10y + 2x)
3. tdk bsa difaktorkan 4x^2y^2 - 9z^2
4. x^2 - 44(x - z)^2
= x^2 - 44 ( x^2 - 2xz + z^2)
= x^2 - 44x^2 + 88xz - 44z^2
= - 43x^2 + 88xz - 44z^2
5. (x - y)^ - 4( x-y)^2
= x^2 - 2xy + y^2 - 4 ( x^2 - 2xy + y^2)
= x^2 - 2xy + y^2 - 4x^2 + 8xy - 4y^2
= -3x^2 + 6xy - 3y^2
= ( -3x -3y)(x + y)
