Hi
factoring
2. 4x^24 - y^2 Note the use of ^ to indicate square (uppper case 6 on keyboard)
(2x -y)(2x +y)Note:SUM of the inner product(-2xy) and the outer product(2xy) = 0
3.4x^2 - 64y^2  
(2x - 8y)(2x+8y)Note:SUM of the inner product(-16xy) and the outer product(16xy) = 0
4. x^2 - 16^y2 
(x-4y)(x+4y)Note:SUM of the inner product(-4xy) and the outer product(4xy) = 0
