Question

The coefficients of the expression 7x^4-9x^3+2x^2 are:



a.4, 3, 2
b.4, -3, 2
c. 7, 9, 2
d. 7, -9, 2

Answer 1

If you have \(5x^2\), 5 is the coefficient.

Answer 2

help

Answer 3

And in \(-6x^5\) it would be -6 (don't forget the negative sign).

Answer 4

It works the same way in the equation you gave.

Answer 5

is it a, b, c, d

Answer 6

You need to have some idea of how to solve this, just giving you the answer without understanding isn't going to help you in the long run.

Answer 7

The first term of your expression is \(7x^4\), given what I just said, what do you think the coefficient is?

Answer 8

c

Answer 9

c is close, but you forgot about the negative sign on -9.

Answer 10

d

Answer 11

Yeah.

Answer 12

thank you
