Which expression is equivalent to (-7m^4+15m^3-12m^2)+(3m^5-12m^4-7m^ 3)/m-6?

Simplify the following: -7 m^4 + 15 m^3 - 12 m^2 + (3 m^5 - 12 m^4 - 7 m^3)/m - 6m | | 3 m^4 | - | 12 m^3 | - | 7 m^2 | + | 0 m | + | 03 m^5 | - | 12 m^4 | - | 7 m^3 | + | 0 m^2 | + | 0 m | + | 03 m^5 | + | 0 m^4 | | | | | | | |    | | -12 m^4 | - | 7 m^3 | | | | | |    | | -12 m^4 | + | 0 m^3 | | | | | |    | | | | -7 m^3 | + | 0 m^2 | | | |    | | | | -7 m^3 | + | 0 m^2 | | | |    | | | | | | | | 0 | |    | | | | | | | | 0 | |    | | | | | | | | | | 0  | | | | | | | | | | 0  | | | | | | | | | | 0: 3 m^4 - 12 m^3 - 7 m^2 - 7 m^4 + 15 m^3 - 12 m^2 - 6grouping like terms, 3 m^4 - 7 m^4 + 15 m^3 - 12 m^3 - 7 m^2 - 12 m^2 - 6 = (-7 m^4 + 3 m^4) + (15 m^3 - 12 m^3)  + (-12 m^2 - 7 m^2) - 6: (-7 m^4 + 3 m^4) + (15 m^3 - 12 m^3) + (-12 m^2 - 7 m^2) - 63 m^4 - 7 m^4 = -4 m^4: -4 m^4 + (15 m^3 - 12 m^3) + (-12 m^2 - 7 m^2) - 615 m^3 - 12 m^3 = 3 m^3: -4 m^4 + 3 m^3 + (-12 m^2 - 7 m^2) - 6-12 m^2 - 7 m^2 = -19 m^2: -4 m^4 + 3 m^3 + -19 m^2 - 6factor -1 out of -4 m^4 + 3 m^3 - 19 m^2 - 6: answer: -(4 m^4 - 3 m^3 + 19 m^2 + 6)

step-by-step explanation:

when the line is solid:

it's either < or >

when the line is dashed:

it's either < or >

about the problem:

since the line is solid, that means it's either < or >
