Determine the nature of the roots 2x 2+8x+3 0
WebUse Descartes' Rule of Signs to find the number of real roots of:f (x) = x5 + 4x4 − 3x2 + x − 6. First, I look at the positive-root case, which is looking at f (x): f ( x) = +x5 + 4 x4 − 3 x2 + x − 6. The signs flip three times, so there are three positive roots, or one positive root. Either way, I definitely have at least one positive ... WebThe discriminant is \({b^2} - 4ac\), which comes from the quadratic formula and we can use this to find the nature of the roots. Roots can occur in a parabola in 3 different ways as …

WebA quadratic function can be in different forms: standard form, vertex form, and intercept form. Here are the general forms of each of them: Standard form: f(x) = ax 2 + bx + c, where a ≠ 0.; Vertex form: f(x) = a(x - h) 2 + k, where a ≠ 0 and (h, k) is the vertex of the parabola representing the quadratic function. Intercept form: f(x) = a(x - p)(x - q), where a ≠ 0 … WebApr 8, 2024 · 1. Discuss the nature of the roots of a quadratic equation 2x 2 – 8x +3 = 0. Solutions: Here, the coefficients are all rational. The discriminant D for a given equation will be. D = b 2 – 4ac = (-8) 2-4*2*3 =64-24 = 40 > 0. We can see, the discriminant of the given quadratic equation is positive but not a perfect square.
WebA root is a value for which the function equals zero. The roots are the points where the function intercept with the x-axis; What are complex roots? Complex roots are the … WebThe Discriminant tells about the nature of the roots of quadratic equation. In ... As discriminant is zero, so it has one real root. Example 3: \(x^2 – 2x + 3 = 0\) For D: \(Δ = b^2 – 4ac = (-2)^2 – 4(1)(3) = 4 – 12 = -8\). As discriminant is negative, so it has no real solution. ... The determinant (Δ) determine the nature of the ...
