i will medal and fan you!
1.(–10x3 + 30x – 20) ÷ (–5x + 5)
2.(8m7 – 10m5) ÷ 2m3
3.(–6m9 – 6m8 – 16m6) ÷ (2m3)
these kinds of questions confuse the heck out of me please help and explain(:

Best ResponseYou've already chosen the best response.0these are the questions. sorry i wrote them down wrong: (10x^3+30x20) / 5x+5 (8m^7 – 10m^5) ÷ 2m^3 (–6m^9 – 6m^8 – 16m^6) ÷ (2m^3)

Best ResponseYou've already chosen the best response.0\[\frac{ 10x^3+30x20 }{ 5x+5 }=\frac{ 10(x^33x+2) }{ 5(x1) }=\frac{ 5*2( x^33x+2) }{ 5(x1) }\] do u see anything common in both denominator and numerator?
