If a ≠ 1, what will be the degree of (a - 1)x^10 + 7x^4 - 8?

Answer and explanation

Correct answer: 10

The governing concept is that the degree is determined by the highest power whose coefficient is non-zero. In this polynomial, the coefficient of x^10 is a - 1. The condition a ≠ 1 guarantees that a - 1 ≠ 0, so the x^10 term is present and cannot disappear. Since x^10 has a higher power than x^4 and the constant term has power 0, the degree of the polynomial is 10. Therefore option C is correct. Option A selects the degree of the lower non-constant term and would be relevant only if the x^10 coefficient vanished. Option B is not an exponent present in the expression, and option D confuses the degree with a coefficient or with the difference a - 1. The condition on a is precisely what preserves the leading term.
