Question

Subtract – 4xy + 4xy2 – 4p from 9xy + 11xy2 – 9p.​

Answer 1

9xy+11xy²-9p — (-4xy)+4xy²-4p

=> 9xy+11xy²-9p + 4xy+4xy²-4p

=> 9xy+4xy+11xy²+4xy²-9p-4p

=> 13xy+15xy²-5p

Answer 2

Given: $(9xy + 11xy^2 -9p)-(-4xy + 4xy^2 -4p)$

We have to solve the above expression.

• As we know that the subtraction is an arithmetic operation that represents the operation of removing objects from a collection.
• Subtraction is denoted by the minus(-) sign.  

We are solving in the following way:

We have,

$(9xy + 11xy^2 -9p)-(-4xy + 4xy^2 -4p)$

Solving like terms:

$=>9xy + 11xy^2 -9p+4xy - 4xy^2 +4p\\=>9xy+4xy+ 11xy^2- 4xy^2-9p+4p\\=>13xy+7xy^2-5p$

Hence, the solution of the above equation is$13xy+7xy^2-5p$.
