Sum and Product of Roots of Quadratic Equation. We have seen that the roots of the quadratic equation x 2 - 7x + 10 = 0 are x = 2 and x = 5. So the sum of its roots = 2 + 5 = 7 and the product of its roots = 2 × 5 = 10.

WebSo what do I mean by non-real roots? Well, if this expression right here-- if this B squared minus 4AC-- if that's a negative number, then I'm going to have to take the square root of a negative number. So it will actually be an imaginary number, and so this whole term will actually become complex. We'll have a real part and an imaginary part. WebNonreal roots [ edit] Any n th degree polynomial has exactly n roots in the complex plane, if counted according to multiplicity. So if f ( x) is a polynomial with real coefficients which does not have a root at 0 (that is a polynomial with a nonzero constant term) then the minimum number of nonreal roots is equal to fluid in baby stomach at 20 week scan
