Name two types of errors and state how each is minimized when measuring the length of objects

Some types of errors are:

Environmental Error Instrumental Errors Observational Errors.Random Errors.

Explanation:

Ways to minimize errors are:

Double check all measurements for accuracy.Double check your formulas are correct.Make sure observers and measurement takers are well trained.Make the measurement with the instrument that has the highest precision.Take the measurements under controlled conditions.

The great common factor is:

x(2z)²

Steps:

given:

4x²yz³12xz²

4x²yz³ = 2²x²z²yz

4x²yz³ = x(2z)²xyz

12xz² = 4×3xz²

12xz² = 2²3xz²

12xz² = x(2z)²3

The great common factor is: x(2z)²
