Respuesta :

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 : [tex]3ab^{2}[/tex]

Step-by-step explanation:

The giving terms are:

[tex]2ab^{2}+(-5ab^{2} )[/tex]

The sum is = [tex]-3ab^{2}[/tex]

Now, its asked that [tex]-3ab^{2}[/tex] is the same as sum of [tex]-6ab^{2}[/tex] and an undefined term.

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

[tex]x+(-6ab^{2} )=-3ab^{2}[/tex]

[tex]x-6ab^{2} =-3ab^{2}[/tex]

[tex]x=-3ab^{2}+6ab^{2}[/tex]

[tex]x=3ab^{2}[/tex]

So, the term is : [tex]3ab^{2}[/tex]
