Question

Find the sum of 3x2 – 2x + 9 and the quotient of xyz(x+y)(y+z)(z+x) divided by xy2+xyz​

Answer 1

Step-by-step explanation:

Take 2nd term xyz(x+y) (y+z) (z+x) /(xy^2+xyz) =xyz(x+y) (y+z) (z+x) /xy(y+z)

On solving, =z(x+y) (z+x) =z(xz+yz+x^2+xy) =xz^2+yz^2+x^2z+xyz

Add3x^2-2x+9 and xz^2+yz^2+x^2z+xyz, we get

=x^2(3+z) +x(z^2-2+yz) +yz
