2ab^2 + (-5ab^2) = 2ab^2 - 5ab^2 = - 3ab^2

the ab^2's stay the same...ur just messing with the coefficients.
so -3 + what is -6 ? -3 + (-3) = -6

therefore, -6ab^2 + (-3ab^2) = -6ab^2 - 3ab^2 = -3ab^2

so ur answer is : -3ab^2

Answer:

The term is : \(3ab^{2}\)

Step-by-step explanation:

The giving terms are:

\(2ab^{2}+(-5ab^{2} )\)

The sum is = \(-3ab^{2}\)

Now, its asked that \(-3ab^{2}\) is the same as sum of \(-6ab^{2}\) and an undefined term.

so, lets suppose the undefined term to be 'x'

\(x+(-6ab^{2} )=-3ab^{2}\)

\(x-6ab^{2} =-3ab^{2}\)

\(x=-3ab^{2}+6ab^{2}\)

\(x=3ab^{2}\)

So, the term is : \(3ab^{2}\)
