Step-by-step explanation:

Given polynomial

We have to subtract the given polynomials.

Consider

Subtract (1) - (2) , we have,

rewrite by applying plus-minus rule , we have,

Grouping like terms, (like term are terms with same variable having same degree)

Solving , we get,

Thus,

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
