    these are the questions. sorry i wrote them down wrong: (-10x^3+30x-20) / -5x+5 (8m^7 – 10m^5) ÷ 2m^3 (–6m^9 – 6m^8 – 16m^6) ÷ (2m^3)

    \(-10x^3+30x-20=-10x^3+3*10x-2*10\) do u see anything common to all three terms?

    \[\frac{ -10x^3+30x-20 }{ -5x+5 }=\frac{ -10(x^3-3x+2) }{ -5(x-1) }=\frac{ -5*2( x^3-3x+2) }{ -5(x-1) }\] do u see anything common in both denominator and numerator?
