1.Use the quadratic formula to prove that the roots of such an equation must have -a/b as their sum and a/c as their product.2.Prove that the sum of the squares of the roots of such an equation is a/b-2ac.(Hint):Consider(r1+r2).Derive an expression for r1+r2 from this.) ...
The quadratic formula is a formula used to find the roots of a quadratic equation: f(x)=ax^2+bx+c. The formula takes the values of a, b, and c of the equation and outputs the roots of the equation. The formula is x=(-b +- sqrt(b^2-4ac))/(2a). How do you prove the qua...
Roots of Polynomials Solving a polynomial requires finding the values of x. All solutions of x in a polynomial are called the roots of the polynomial. The first step is to set the equation equal to 0, eliminating the variable y. Graphically, the solutions to all polynomials are the x-...
