What is the coefficient of the term of degree 4 in this polynomial?
x^8+2x^4 - 4x^3 + x^2-1

2

Explanation:

Degree 4 is the term with the exponent that is 4. The 2 in front of the x is the coefficient.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
