Question

5x2y-5x2+3yx2-3y2+x2 -y2+8xy2-3y2

Answer 1

SOLUTION

TO CALCULATE

$\sf{5 {x}^{2} y - 5 {x}^{2} + 3y {x}^{2} - 3 {y}^{2} + {x}^{2} - {y}^{2} + 8x {y}^{2} - 3 {y}^{2} }$

EVALUATION

$\sf{ = 5 {x}^{2} y + 3y {x}^{2} - 5 {x}^{2} + {x}^{2} - 3 {y}^{2} - {y}^{2} - 3 {y}^{2}+ 8x {y}^{2} }$

$\sf{ = 5 {x}^{2} y + 3 {x}^{2}y - 5 {x}^{2} + {x}^{2} - 3 {y}^{2} - {y}^{2} - 3 {y}^{2}+ 8x {y}^{2} }$

$\sf{ = (5 + 3) {x}^{2} y - (5 - 1) {x}^{2} -( 3 + 3 + 1) {y}^{2} + 8x {y}^{2} }$

$\sf{ = 8 {x}^{2} y - 4 {x}^{2} - 7 {y}^{2} + 8x {y}^{2} }$
