From what will the degree of (8x^3+4x^2-7x+12) be obtained?
Answer and explanation
Correct answer: From the highest power 3 of x
The degree of a polynomial is the highest power of its variable having a non-zero coefficient. Here, the powers of x are 3, 2, 1, and 0, so the highest power is 3 and the polynomial has degree 3. The number 8 is only a coefficient, not the degree. Exam tip: To find the degree, look for the term with the greatest exponent of the variable.
