Formula of sum of roots

WebThe formula for the root of linear polynomial such as ax + b is. x = -b/a. The general form of a quadratic polynomial is ax 2 + bx + c and if we equate this expression to zero, we get a quadratic equation, i.e. ax 2 + bx + c = 0. The roots of quadratic equation, whose degree is two, such as ax 2 + bx + c = 0 are evaluated using the formula; WebThe roots of the equation we are seeking will be 2α, 2β 2 α, 2 β. The sum and product of the roots will be: S = 2α+2β = 2(α+β) = −2a P = (2α)(2β) =4αβ= 4b S = 2 α + 2 β = 2 ( α …
