numerical coefficient of algebraic expressions?

Question

find out the numerical coefficient of each term of the following algebraic expression (also plz.explain the solution as i am weak in maths.)
x3-7x2y+5xy2-2

Answer 1

I'll do the second term. You can try your hand at the others.

-7x2y = -14xy

(Write each term as a number followed by variables)

the numerical coefficient is whatever the number is in the simplified term. In this case, -14.

Answer 2

Numerical coefficient--as its name implies, it is a number.

I guess that's simple enough.

To be able to get the answer, combine the light terms.

I think you're trying to write x cube minus 7x squared y plus 5xy squared minus two, right?
