Finding the number of solutions

WebA "root" is when y is zero: 2x+1 = 0. Subtract 1 from both sides: 2x = −1. Divide both sides by 2: x = −1/2. And that is the solution: x = −1/2. (You can also see this on the graph) We can also solve Quadratic Polynomials using basic algebra (read that page for an explanation). 2. By experience, or simply guesswork. WebMay 21, 2024 · To find the number of real solutions we calculate what’s called the discriminant: b 2 - 4ac. b 2 - 4ac = (-1) 2 - 4 (1) (5) = 1 - 20 = -19 Whenever the discriminant is negative that means we have zero real solutions.

WebJun 8, 2024 · Now supposed that c is divisible by g , then we have: a ⋅ x g ⋅ c g + b ⋅ y g ⋅ c g = c. Therefore one of the solutions of the Diophantine equation is: x 0 = x g ⋅ c g, y 0 = y g ⋅ c g. The above idea still works when a or b or both of them are negative. We only need to change the sign of x 0 and y 0 when necessary.
