Exercise 11 (B) | Q 4.3

Identify the term, their coefficients for the following expression:

3x²y² − 5x²y²z² + z²

Write the coefficient of: xy in – 3axy

Write the degree of the following polynomial: 2y²z + 9yz³

Group the like term together: 9x², xy, – 3x², x² and – 2xy

Add : 4 + x, 5 – 2x and 6x

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

Simplify: `"x" - ("3y" - bar"4x - 3x" + 2z - bar"5y - 7x")`
