Question

subtract x³-2xy²+5x²y-6 from x³+3x²y+3xy²-2. please answer me it is urgent​

Answer 1

$The \: subtraction \: is \: carried \: out \: as \: follows,</p><p>(y3−3xy2−4x2y)−(x3+2x2y+6xy2−y3)</p><p></p><p>=y3−3xy2−4x2y−x3−2x2y−6xy2+y3</p><p></p><p> \\ Re-arranging \: the \: like \: terms \: together,</p><p>=(y3+y3)+(−3xy2−6xy2)+(−4x2y−2x2y)−x3</p><p></p><p>=2y3−9xy2−6x2y−x3</p><p></p><p> </p><p>$

• OR

The subtraction is carried out as follows,

(y3−3xy2−4x2y)−(x3+2x2y+6xy2−y3)

=y3−3xy2−4x2y−x3−2x2y−6xy2+y3

Re-arranging the like terms together,

=(y3+y3)+(−3xy2−6xy2)+(−4x2y−2x2y)−x3

=2y3−9xy2−6x2y−x3
