8x^2+8x+10+13/(x-1)

Explanation:

"another way to do division is to use the divisor as a"
"factor in the numerator"

"consider the numerator"

color(red)(8x^2)(x-1)color(magenta)(+8x^2)+2x+3

=color(red)(8x^2)(x-1)color(red)(+8x)(x-1)color(magenta)(+8x)+2x+3

=color(red)(8x^2)(x-1)color(red)+8x)(x-1)color(red)(+10)(x-1)color(magenta)(+10)+3

=color(red)(8x^2)(x-1)color(red)(+8x)(x-1)color(red)(+10)(x-1+13

"quotient "=color(red)(8x^2+8x+10)," remainder "=13

rArr(8x^3+2x+3)/(x-1)=8x^2+8x+10+13/(x-1)
