which expression can be used to find the difference of the polynomials?\n$(10m - 6) - (7m - 4)$\n$\\bigcirc\\ 10m + (-7m) + (-6) + 4$\n$\\bigcirc\\ (10m + 7m) + (-6) + (-4)$\n$\\bigcirc\\ (-10m) + (-7m) + (6 + 4)$\n$\\bigcirc\\ 10m + (-7m) + 6 + (-4)$

which expression can be used to find the difference of the polynomials?\n$(10m - 6) - (7m - 4)$\n$\\bigcirc\\ 10m + (-7m) + (-6) + 4$\n$\\bigcirc\\ (10m + 7m) + (-6) + (-4)$\n$\\bigcirc\\ (-10m) + (-7m) + (6 + 4)$\n$\\bigcirc\\ 10m + (-7m) + 6 + (-4)$

Answer

Explanation:

Step1: Distribute the negative sign

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

Step2: Group like terms

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

Answer:

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