Predict the result
Algebra connects equivalent expressions, equations, proportions, and inequalities.
Identify the coefficient, variable part, and degree of negative eight z cubed.

Set up the model
Separate the numerical multiplier from the variable part.
The exponent gives the degree of this single-variable term.

Work the example
The coefficient is negative eight and the variable part is z cubed.
The degree is three.

Check the result
Now identify these parts for r squared.
Take eight seconds to think before the answer appears.
[Eight-second silent pause to work; the answer remains hidden.]
The coefficient is one, the variable part is r squared, and the degree is two.

Interpret the result
A coefficient of one can be written implicitly, but it still multiplies the variable part.
