Question

1. Identify the name and label the parts of the following polynomial: -2x4+24x2-10

Answer 1

Please write this polynomial as P(x) = -2x^4+24x^2-10, using " ^ " to denote exponentiation.

This is a fourth degree polynomial, since the highest power of x is 4.  Ordinarily, a fourth degree poly would have 5 terms, but here two of the coefficients of the powers of x are zero, leaving only 3 terms.

The lead coeff. of  P(x) = -2x^4+24x^2-10  is -2.

The constant terms is -10.  The exponent of x here is zero (0).

The degree of the middle term is 2 (see 24x^2, above)

Would you please post your other questions separately.  Thank you.
