What are the applications of roots of a polynomial?

[QUOTE="symbolipoint, post: 5794545, member: 58864"] pairofstrings You know something about roots of polynomial (or at least for quadratic) equations. You give a description more in line with finding the solution of a SYSTEM of quadratic equations. You are asking in effect, given x^2+7x+12=0 and x^2+8x+12=0, where do the FUNCTIONS which the left-hand members intersect? If that is what you are asking, then x^2+7x+12=x^2+8x+12. You can solve this. Subtract x^2 and 12, from both sides. 7x=8x 0=8x-7x 0=x The two FUNCTIONS would seem to intersect at point (0,12). Keep studying and this will become clear (if not today, then sometime during Intermediate Algebra). [/QUOTE]
