First Polynomial Details: First polynomial is $5x^{2}-8x+2$ . Coefficients are the numbers in front of the variables, so for $5x^{2}$ , the coefficient is $5$ . For $-8x$ , the coefficient is $-8$ . The constant is the term without a variable, which is $2$ . The degree of a polynomial is the highest power of the variable, so the degree here is $2$ because of the term $5x^{2}$ . The variable is $x$ .
Second Polynomial Details: Second polynomial is $-6x-7$ . Coefficients are $-6$ for $-6x$ . The constant is $-7$ . This polynomial has only one variable term, so the degree is $1$ . The variable is $x$ .
Third Polynomial Details: Third polynomial is $-10x^{2}+3x$ . Coefficients are $-10$ for $-10x^{2}$ and $3$ for $3x$ . There is no constant term (a term without a variable), so the constant is $0$ . The degree is $2$ because of the term $-10x^{2}$ . The variable is $x$ .
