Subtract: −xy + yz − zx from xy − yz + xz - Mathematics

Subtract: −xy + yz − zx from xy − yz + xz

Sum

Find the value of (xy + yz + zx) − (−xy + yz − zx)

We need to subtract (−xy + yz − zx) from (xy – yz + zx)

= (xy – yz + zx) − (−xy + yz − zx)

= xy – yz + zx + xy – yz + zx

= xy + xy – yz – yz + zx + zx

= 2xy − 2yz + 2zx

the answer is (2xy − 2yz + 2zx)
