How to find a when the quadratic equation has equal roots?

WebThe complex roots always occur in pairs. i.e., if a + bi is a root then a - bi is also a root. Nature of Roots When D = 0. Then the above formula becomes, x = (-b ± √ 0)/2a = -b/2a. and hence the equation has only one real root. Thus, the quadratic equation has only one real root (or two equal roots -b/2a and -b/2a) when b 2 - 4ac = 0. WebA polynomial equation whose degree is 2, is known as quadratic equation. A quadratic equation in its standard form is represented as: ax2 + bx + c = 0, where a, b and c are real numbers such that a ≠ 0 and x is a variable. … WebThen the formula will help you find the roots of a quadratic equation, ... so here a = 1 a = 1 a = 1 a, equals, 1 (note that a a a a can’t equal 0 0 0 0-- the x 2 x^2 x 2 x, squared is what … palazzo vendramin calergi
