X^2+6x+8
= x^2+4x+2x+8
=x(x+4)+2(x+4)
=(x+2) (x+4)
100x^2-80xy+16y^2
=100x^2 -40xy -40xy+16y^2
=10x(10x-4y) -4y(10x-4y)
=(10x-4y)( 10x-4y)
16x^4-y^4
=(4x^2)^2. - (y^2)^2
=(4x^2 - y^2) (4x^2 +y^2)
= x^2+4x+2x+8
=x(x+4)+2(x+4)
=(x+2) (x+4)
100x^2-80xy+16y^2
=100x^2 -40xy -40xy+16y^2
=10x(10x-4y) -4y(10x-4y)
=(10x-4y)( 10x-4y)
16x^4-y^4
=(4x^2)^2. - (y^2)^2
=(4x^2 - y^2) (4x^2 +y^2)
