5x²y-5x²+3yx²-3y²+x²-y²+8xy²-3y² Solution with explanation :- Explanation - 1st we have to bring like terms forward of each terms means terms of ( x²y , yx² = x²y , x² , y² , xy ) . I have typed that yx² = x²y , keep this in mind . 2nd we have to do grouping of each terms as shown , consider that " ( 5 + 3 ) x²y + ( -5 + 1 ) x² + ( -3 -1 -3 ) y² + 8xy " So we get answer by adding them, so answer of example is " 8x²y -4 x² -7y² + 8xy " If not understand you will get clear after seeing answer of the question. Solution - 5x²y + 3x²y -5x² + x² -3 y² -y² -3 y² + 8xy = ( 5 + 3 ) x²y + ( -5 + 1 ) x² + ( -3 -1 -3 ) y² + 8xy = 8 x²y -4 x² -7 y² + 8xy ( We get answer by adding ) .
