Question

In the expression, 2y2 + 4x – y + x2 +8, what is the coefficient

of x2 ?
A- 8
B- 2
C- 1
D- 4

Answer 1

C. 1

Explanation:

There is no number before the
`x^2` term and the term is positive, so the coefficient is
`1` (which is the only number we can refrain from writing as a coefficient, hence the reasoning).
