Question

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)

Explanation:

Step1: Distribute the negative sign

$(10m - 6) - (7m - 4) = 10m - 6 -7m +4$

Step2: Group like terms

$=(10m -7m) + (-6 +4) = [10m + (-7m)] + [(-6) +4]$

Answer:

[10m + (-7m)] + [(-6) + 4]
