Question

Add the product : x(x + y - r), y(x - y + r), z(x - y - x)​

Answer 1

Step-by-step explanation:

x(x+y-n),y(x-y+r),z(x-y-x)

Answer

2x+xy-xn+yx-2y+yr+zx-zy-zx

xy+yx+zx-zx+2x-xn-2y+yr-zy

2xy+2x-xn-2y-yr-zy

Answer 2

$\huge\tt{❥Answer}$

${x}^{2} + xy - rx + xy - {y}^{2} + ry + xz \\ - yz - {z}^{2} \\ {x}^{2} - {y}^{2} - {z}^{2} + 2 xy - rx + ry + xz \\ - yz \\ {x}^{2} - {y}^{2} - {z}^{2} + 2xy - r(x + y) + z \\ (x - y)$
