Which of the following are like terms?
5xy, -3xz
5xy, 5yz
-5xy, 7xy
5xy,
Like terms are the terms that contain same variables raised to the same power, the coefficients need not be same. −5xyz2, 7xyz2 are like terms.
When 7xy+5yz−3zx, 4yz+9zx−4y and −3xz+5x−2xy are added, we get 5xy+9yz+3zx+5x−4y.
Find the value of A+B+C if : A=(7xy+5yz−3zx) B=(4yz+9zx−4y) C=(−3xz+5x−2xy)
Among x3, 4xy, 3y2, 3x2 and 5xy, which are like terms?
4xy−5yz−7z
–5xy+2yz+zx
–2xy−3yz+3zx
