Question

Find the sum of the following expressions

$\frac{3}{2} {x}^{2} y - \frac{1}{2}xy + \frac{7}{2} - 2 + 3 {x}^{2}y + 2xy - \frac{1}{2} {x}^{2} y + \frac{3}{2} xy - \frac{3}{2}$
​

Answer 1

Answer:

Step-by-step explanation:

3/2x^2y+3x^2y-1/2x^2y-1/2xy+2xy+3/2xy+7/2-2-3/2

(3x^2y+6x^y-x^2y-xy+4xy+3xy+7-4-3)/2

(8x^2y-6xy)/2

2(4x^2y-3xy)/2

4x^2y-3xy

xy(4x-3)
