Determining the nature of roots
WebAug 1, 2024 · So, given: x 2 + a x + a 2 = 0. Using the quadratic formula: a = 1, b = a, c = a 2. Therefore, the discriminant is: a 2 − 4 ( 1) ( a 2) = a 2 − 4 a 2 = − 3 a 2. As we're squaring a, it will always be non-negative. However, as we're multiplying by − 3, the result is always non-positive. To me, that says that if a = 0, there are equal ...

WebSo 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 going to be x is equal to negative b plus or minus the square ... WebNov 20, 2015 · x = 2 or x= -12 are the roots. Discriminant. For an equation ax 2 +bx+c = 0, b 2-4ac is called the discriminant and helps in determining the nature of the roots of a quadratic equation. If b 2-4ac > 0, the roots are real and distinct. If b 2-4ac = 0, the roots are real and equal. If b 2-4ac < 0, the roots are not real (they are complex).
