Question

Subtract z(2x - 3y) from the sum of X(2x - 3y + z) and y(2x - 3y + z)​

Answer 1

Answer:

Sum of x(2x-3y +z) and y(2x-3y +z)

= 2x- 3y+z +2x-3y+z

=4x-6y+2z

Now subtracting z(2x-3y)

=4x-6y+2z-(2x-3y)

=4x-6y+2z-2x+3y

=2x - 3y+2z

Hope it helps!

Answer 2

Answer:

x(2x-3y+ z)+ y(2x- 3y+z) -z(2x-3y)

$2x {}^{2} - 3yx + zx + 2xy - 3y {}^{2} + zy - 2xz + 3yz \\ \\ 2x {}^{2} { - 3y}^{2} - xy - zx + 4yz$
