2x+16+80/(x+4)2x+16+80x+4

Explanation:

"one way is to use the divisor as a factor in the numerator"one way is to use the divisor as a factor in the numerator

"consider the numerator"consider the numerator

color(red)(2x)(x-4)color(magenta)(+8x)+8x+162x(x4)+8x+8x+16

=color(red)(2x)(x-4)color(red)(+16)(x-4)color(magenta)(+64)+16=2x(x4)+16(x4)+64+16

=color(red)(2x)(x-4)color(red)(+16)(x-4)+80=2x(x4)+16(x4)+80

"quotient "=color(red)(2x+16)," remainder "=80quotient =2x+16, remainder =80

(2x^2+8x+16)/(x-4)=2x+16+80/(x-4)2x2+8x+16x4=2x+16+80x4
