WebInteractive online graphing calculator - graph functions, conics, and inequalities free of charge WebThe two known roots have sum 2, so the missing root must be − 2. If the leading term of the polynomial has coefficient 1, then the product of its roots gives the free term. Your polynomial has real coefficients; if 1 − 2 i is a root, then so is 1 + 2 i. Thus, we arrive to 10 = ( 1 − 2 i) ( 1 + 2 i) a, where a is the real root.
