Best ResponseYou've already chosen the best response.0alright then for long division 5 steps) \(\huge\color{green}{{1:}}\) Divide the first terms \(\huge\color{green}{{2:}}\) multiply(distribute) \(\huge\color{green}{{3:}}\) subtract all terms \(\huge\color{green}{{4:}}\) carry down \(\huge\color{green}{{5:}}\) repeat dw:1432748779555:dw there isn't any x^2 term but we still have to write it

Best ResponseYou've already chosen the best response.0first step divide first terms \[\huge\rm \frac{ 10x^3 }{ 5x } = ?\]

Best ResponseYou've already chosen the best response.0and x^3 is same as \[\huge\rm \frac{ x \times x \times x }{ x }\]

Best ResponseYou've already chosen the best response.0and x^3 is same as \[\huge\rm \frac{ x \times x \times \cancel{ x} }{\cancel{ x} }\] so 2x^2

Best ResponseYou've already chosen the best response.0now distribute divisor by 2x^2 dw:1432749473531:dw 2x^2 (5x+5) = ??
