Which of the following is/are correct in factorization?
x^26x16=(x8)(x+2)
x^2y^210xy+16=(xy+2)(xy+8)
x^25xy+6y^2=(x2)(x3)
x^2+13xy30y^2=(x10y)(x3y)
x^26x16
=x^28x+2x16
=x(x8)+2(x8)
=(x8)(x+2)
Correct
x^2y^210xy+16
=x^2y^28xy2xy+16
=xy(xy8)2(xy8)
=(xy2)(xy8)
Therefore
(xy+2)(xy+8) is not correct
x^25xy+6y^2
=x^23xy2xy+6y^2
=x(x3y)2y(x3y)
=(x2)(x3)
Correct
x^2+13xy30y^2
=x^22xy+15xy30y^2
=x(x2y)+15y(x2y)
=(x+15y)(x2y)
Therefore
(x10y)(x3y) is not correct
