2x2 + 3yx2 + 10xy + 15y2 + 13y + 10x2 + 2x + 10
2x3 + 6yx2 + 5xy + 15y2 + 31y + 5x2 + 2x + 10
2x3 + 6xy2 + 5xy + 15y2 + 12y + 10x2 + 2x = 10
2x2 + 6xy2 + 5xy + 15y2 + 13y + 10x2 + 2x + 10
2x3 + 2yx2 + 10xy + 10y2 + 31y + 5x2 + 10
Correct answer is B
(x+3y+5)(2x2+5y+2)
= 2x3+5xy+2x+6yx2+15y2+6y+10x2+25y+10
= 2x3+5xy+2x+6yx2+15y2+31y+10x2+10
