Question

7 - 2x - x4

b) How many terms are there?
c) What is the leading coefficient?
d) What is the constant term?
e) What is the degree of the expression?

Answer 1

b) three terms

c) -1

d) 7

e) 4

Explanation:

put the expression in decreasing exponent order with the constant at the end

-x⁴ - 2x + 7

With this format it is easy to find the leading coefficient which is the coefficient of the term with the highest exponent; in this case you only see a negative sign but every variable, if no other coefficient is present, has an invisible '1'
