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. 15xyz2, 45xyz2 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)
Which of the following are like terms? (a) 5xyz2,-3xy2z (b) –5xyz2,7xyz2 (c) 5xyz2,5x2yz (d) 5xyz2,x2y2z2
Add the following:
3xy,-5xy,7xy
Simplify the following : 7xy+4xy-3xy-11xy+5xy-xy
