Question

( 7xy²+ 3y ) - ( 5xy² + 2yx²)

Answer 1

Answer:

$(7x {y}^{2} + 3y) - (5x {y}^{2} + 2y {x}^{2} ) \\ = 7x {y}^{2} + 3y - 5x {y}^{2} - 2y {x}^{2} \\ = 7x {y}^{2} - 5x {y}^{2} + 3y - 2y {x}^{2} \\ = 2x {y}^{2} + 3y - 2y {x}^{2} \\ = 2x {y}^{2} - 2y {x}^{2} + 3y$

Answer 2

Answer:

(7xy2+3y)−(5xy2+2yx2)=7xy2+3y−5xy2−2yx2=7xy2−5xy2+3y−2yx2=2xy2+3y−2yx2=2xy2−2yx2+3y
