Which expression can be used to find the difference of the polynomials? (10m - 6) - (7m - 4)
[10m + (-7m)] + [(-6) + 4]
(10m + 7m) + [(-6) + (-4)]
[(-10m) + (-7m)] + (6 + 4)
[10m + (-7m)] + [6 + (-4)]
Solution:
(10m - 6) - (7m - 4) [Given]
We have to find the expression that can be used to find the difference of the polynomials
= 10m - 6 - 7m + 4
We can write it as
= 3m - 2 ….. (1)
Consider
[10m + (-7m)] + [(-6) + 4]
By further calculation
= 10m - 7m - 6 + 4
So we get
= 3m - 2 …. (2)
As (1) and (2) are same
The expression [10m + (-7m)] + [(-6) + 4] can be used to find the difference of the polynomials.
Therefore, the expression [10m + (-7m)] + [(-6) + 4] can be used to find the difference of the polynomials.
Which expression can be used to find the difference of the polynomials? (10m - 6) - (7m - 4)
[10m + (-7m)] + [(-6) + 4]
(10m + 7m) + [(-6) + (-4)]
[(-10m) + (-7m)] + (6 + 4)
[10m + (-7m)] + [6 + (-4)]
Summary:
The expression which can be used to find the difference of the polynomials (10m – 6) – (7m – 4) is [10m + (-7m)] + [(-6) + 4].
