Quadratic formula if b is already negative
WebTo solve a quadratic equation, use the quadratic formula: x = (-b ± √(b^2 - 4ac)) / (2a). What is the quadratic formula? The quadratic formula gives solutions to the quadratic equation ax^2+bx+c=0 and is written in the form of x = (-b ± √(b^2 - 4ac)) / (2a) Does any quadratic equation have two solutions? There can be 0, 1 or 2 solutions ... WebIf a quadratic is missing either the bx or c term, then set b or c equal to 0. If the quadratic does not contain the ax2 term, you cannot use the quadratic formula because the denominator of the quadratic formula will equal 0. In that case, you can use algebra to find the zeros. Using the quadratic equation

WebSep 5, 2024 · The Quadratic Formula is a useful way to solve these equations, or any other quadratic equation! The Quadratic Formula, x = − b ± √b2 − 4ac 2a, is found by completing the square of the quadratic equation ax2 + bx + c = 0. The discriminant of the Quadratic Formula is the quantity under the radical, b2 − 4ac. WebThis is because if you have -1/3 And make it (-1)/ (-3) it isn't -1/3 anymore it's 1/3 so that isn't correct also (-1)/3 is equal to 1/ (-3) as it's still 1/3 and still negative 1/ (-3) is more annoying to use and look at so most people do (-1)/3 So that's …
