The roots of a quadratic equation
Webb11 aug. 2012 · Ok, about them. You should not check values of them at all (only if is said so in your assignment). Instead you have only and exact 3 situations here: when D > 0 - you have 2 different real roots, when D = 0 - you have exactly one real root (or 2 similar roots), and when D < 0 - you do not have any real roots. WebbThe quadratic formula is used when solving a quadratic which cannot be factorised. The quadratic formula is: \[x = \frac{{ - b \pm \sqrt {{b^2} - 4ac} }}{{2a}}\]

WebbAnd we can just review it by looking at the quadratic formula. So if I have a quadratic equation in standard form, ax squared plus bx plus c is equal to 0, we know that the quadratic formula, which is really just derived from completing the square right over here, tells us that the roots of this, or the solutions of this quadratic equation are ... Webb12 apr. 2024 · This is because in this case, the quadratic formula (-b ± sqrt(b^2 – 4ac)) / 2a will yield two distinct real solutions for x. In contrast, if the discriminant is zero (i.e., b^2 …
WebbThe solution to the quadratic equation is given by the quadratic formula: The expression inside the square root is called discriminant and is denoted by Δ: This expression is important because it can tell us about the solution: When Δ>0, there are 2 real roots x 1 = (-b+√ Δ )/ (2a) and x 2 = (-b-√ Δ )/ (2a). When Δ=0, there is one root ...
