subtrct
xy²z² + 3x²y²z – 4x²yz² from -9x²y²z + 3xy²z² + x²yz²

Answer 1

Answer:

-12x²y²z+2xy²z²+5x²yz²

Step-by-step explanation:

-9x²y²z+3xy²z²+x²yz²-(xy²z²+3x²y²z-4x²yz²)

=-9x²y²z+3xy²z²+x²yz²-xy²z²-3x²y²z+4x²yz²

=-12x²y²z+2xy²z²+5x²yz²

Answer 2

Answer:

Solution

$- 9 {x}^{2} {y}^{2} z + 3x {y}^{2} {z}^{2} + {x}^{2} y {z}^{2} \ - \\ (x {y}^{2} {z}^{2} + 3 {x}^{2} {y}^{2} z - 4 {x}^{2} y {z}^{2} ) \\ = - 9 {x}^{2} {y}^{2} z + 3x {y}^{2} {z}^{2} + {x}^{2} y {z}^{2} - \\ x {y }^{2} {z}^{2} - 3 {x}^{2} {y}^{2} z + 4 {x}^{2} y {z}^{2} \\ = - 12 {x}^{2} {y}^{2} z + 2x {y}^{2} {z}^{2} + 5 {x}^{2} y {z}^{2}$
