What is the coefficient of the x2-term of the algebraic expression 2x4 + x2 - x + 7
the x^2 term has a coefficient of 1.....even though it is not written, it is understood.
x^2 is the same as 1x^2
The coefficient of the x^2 term is 1. When there is no number shown as a coefficient it is automatically considered a one.
