WebHow do you calculate a quadratic equation? To 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 … WebMar 4, 2024 · So I am coding something that will include two variables that are taking place of constants in a quadratic equation. We have a quadratic that is equal to the first equation so we can solve it by hand but I want to verify my numbers. However the solutions for K1 and K2 keep getting messed up by the x value (which in this code is deemed l) …

Web(ii) If x=4 is one root of (k+2)x^(2)-(5k+2)x-4=0, find the value of k. Also, find the other root of Quadratic Eq; Question: (ii) If x=4 is one root of (k+2)x^(2)-(5k+2)x-4=0, find the value of k. Also, find the other root of Quadratic Eq WebJun 12, 2024 · We know that quadratic equation ax2 + bx + c = 0 has equal roots if D = b2 – 4ac = 0. Therefore, given quadratic equation x2 – 4kx + k = 0 has equal roots if D = 0. ⇒ (−4k)2 – 4 × 1 × k = 0. (∵ In equation x2 – 4kx + k = 0, a = 1, b = – 4k & c = k) ⇒ 16k2 – 4K = 0 ⇒ 4k (4k – 1) = 0 ⇒ k = 0 or 4k – 1 = 0 ⇒ k = 0 or k = 1 4 1 4 . WebJul 25, 2015 · 2 Answers. Sorted by: 1. If you don't want to incorporate your prior knowledge to the problem, the quadratic equation has equal roots when the discriminant is equal to zero. ( k − 1) 2 + 4 ( 1) ( 1 + 2 k) = k 2 + 6 k + 5 = ( k + 1) ( k + 5) = 0 k ∈ { − 5, − 1 } Share. buck sports barn
