Q. Pick the expression that matches this description:A polynomial of the 5th degree with a leading coefficient of 7 and a constant term of 6Choose 1 answer:(A) 7x5+2x2+6(B) 6x5+x4+7(C) 6x7−x5+5(D) 7x6−6x4+5
Analyze options for degree polynomial: Analyze the given options to identify the polynomial of the 555^{\text{th}} degree.\newlineA polynomial of the 555^{\text{th}} degree must have its highest exponent as 555. This means we are looking for a term with x raised to the power of 555.
Check if options meet criteria: Check each option to see if it meets the criteria of being a 555th-degree polynomial.\newline(A) 7x5+2x2+67x^{5}+2x^{2}+67x5+2x2+6 - This is a 555th-degree polynomial.\newline(B) 6x5+x4+76x^{5}+x^{4}+76x5+x4+7 - This is also a 555th-degree polynomial.\newline(C) 6x7−x5+56x^{7}-x^{5}+56x7−x5+5 - This is not a 555th-degree polynomial; it is a 777th-degree polynomial.\newline(D) 7x6−6x4+57x^{6}-6x^{4}+57x6−6x4+5 - This is not a 555th-degree polynomial; it is a 666th-degree polynomial.
Identify 555th degree polynomial with leading coefficient of 777: Among the 555th-degree polynomials, identify the one with a leading coefficient of 777.\newlineThe leading coefficient is the coefficient of the term with the highest exponent.\newline(A) 7x5+2x2+67x^{5}+2x^{2}+67x5+2x2+6 - The leading coefficient is 777.\newline(B) 6x5+x4+76x^{5}+x^{4}+76x5+x4+7 - The leading coefficient is 666, not 777.
Check constant term of remaining option: Check the constant term of the remaining option.\newlineThe constant term is the term without a variable.\newline(A) 7x5+2x2+67x^{5}+2x^{2}+67x5+2x2+6 - The constant term is 666.
Confirm option (A) meets all criteria: Confirm that option (A) meets all the criteria.\newline(A) 7x5+2x2+67x^{5}+2x^{2}+67x5+2x2+6 is a 555th-degree polynomial with a leading coefficient of 777 and a constant term of 666.
