what is the numerical coefficient of x2 (tiny 2)
i thought a numerical coefficient would i.e. be 4 in 4x, but im stumped because it has the squared number. herlp??

When there is no coefficient written, it is assumed to be 1.0 by convention.......

If you are talking about an x with a tiny two on the bottom right, that is a subscript. Sometimes variables are given subscripts so you can use the same letter, but be talking about different variables: x1,x2, x3, etc. The number is tiny but is down low, instead of being in the raised position of a power. These numbers are not coefficients and are not part of the calculation. The name of this variable is just x-sub-2 instead of plain x. If it has a coefficient, that number would be in front of the x.
I hope that helps.

For example, y=3x^3-2x^2+x-1
This equation has 4 coefficients: 3 for the x^3 term, -2 for the x^2 term, 1 for the x term, and the constant is -1.

your original idea is correct. for a number like x^2, the coefficient would be "1' since there is nothing in front of the "x"

the answer is 1 since that is 1x2 (tiny 2). it is understood that 1 is the numerical coeficient.

It is an implied 1
x^2 = 1x^2
Just like
- (x + 2) = - 1(x + 2)
Even if not written, it is still there
