4d^2y^2 /5ac^3 +3x^2/10a^3d

I will put the bracket just make it clear

2z+(6w/9z) +9z+(2w/6z) -2

=2z + (2w/3z) + 9z +(w/3z) -2

Multiply the eq by 3z you will get

=6z^2 + 2w + 27z^2 + w -6z

=33z^2 +3w -6z = 0

Taking 3 as common you will get

= 3(11z^2 + w - 2z) >>> answer

2z+(6w/9z) +9z+(2w/6z) -2

=2z + (2w/3z) + 9z +(w/3z) -2

Multiply the eq by 3z you will get

=33z^2 +3w -6z = 0
