Question

subract 8x(x-4y+5z) - 9x (2x +y- 3 z)​

Answer 1

Answer:

=8x^2-32xy+40xz-18x^2+9xy-27xz

=8x^2-18x^2-32xy+9xy+40xz-27xz

= -10x^2-23xy+13xz

Answer 2

Answer:

= -10$x^{2}$ - 41xy + 67xz

Step-by-step explanation:

8x(x-4y+5z) - 9x(2x+y-3z)

= (8$x^{2}$-32xy+40xz) - (18$x^{2}$+9xy-27xz)

= 8$x^{2}$-32xy+40xz - 18$x^{2}$ - 9xy + 27xz

= -10$x^{2}$ - 41xy + 67xz
