Question

factorize the following 10 x^2 y +15 xy^2 -25 x^2 y^2

Answer 1

Step-by-step explanation:

2x

2

−15x+27

Coefficient of x

2

=2; constant term =27

Their product =2×27=54

Coefficient of x=−15

∴ product =54; sum =−15

2x

2

−15x+27

=2x

2

−6x−9x+27

=2x(x−3)−9(x−3)

=(x−3)(2x−9)

∴2x

2

−15x+27=(x−3)(2x−9)
