Separate constant terms and variable terms from tile following:

8, x, 6xy, 6 + x, - 5xy² , 15az² , `(32"z")/"xy", "y"^2/"3x"`

Constant is only 8 other is variable 12 – 5 z – 4

Write the coefficient of: mn in -mn

Find the sum of: 4x²+ 8xy – 2y² and 8xy – 5y² + x²

Find the sum of: x² + x – 2, 2x – 3x² + 5 and 2x² – 5x + 7

Simplify: 2x-[5y- (3x -y) + x]

Simplify: 8 [m + 2n-p – 7 (2m -n + 3p)]

Write the greatest common factor in the following terms.

63p²a²r²s, – 9pq²r²s², 15p²qr²s², – 60p²a²rs²

Identify the numerical coefficient of term (other than constant) in the following expression:

0.1 y + 0.01 y²

Identify term and factor in the expression given below:

pq + q
