Question

Find the missing term. The sum of 2ab2 and (-5ab2) is the same as the sum of (-6ab2)

Answer 1

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 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 : $3ab^{2}$
