Question

By how much does the experession 72z^2-45z+4 exceed the expression 30z-42z^2-17​

Answer 1

Required exceeding = 114z² - 75z + 21

Step-by-step explanation:

To find by how much does the experession (72z² - 45z + 4) exceed the expression (30z - 42z² - 17), we simply subtract the second expression from the first expression.

Required exceeding

= (72z² - 45z + 4) - (30z - 42z² - 17)

= 72z² - 45z + 4 - 30z + 42z² + 17

= (72 + 42)z² - (45 + 30)z + (4 + 17)

= 114z² - 75z + 21

Note:

For subtracting one polynomial term from another, we group the coefficients of like terms and use the algebraic operations correctly.
