According to Gauss’s Law, the total electric flux (Φ) through a closed surface is given by: Φ = Qenclosed/ε0 where Qₑ is the total charge enclosed within the surface. The total charge enclosed is: Q enclosed = (+8Q) + (-3Q) ...

The roots of a quadratic equation represent the x-values where the parabola intersects with the x-axis. A quadratic can have two real roots when it crosses the x-axis at two points or one real root when it touches the x-axis ...
The roots of a quadratic equation represent the x-values where the parabola intersects with the x-axis. A quadratic can have two real roots when it crosses the x-axis at two points or one real root when it touches the x-axis ...
Let me explain how to find these values without equations. When we have a quadratic expression with two roots the sum appears as the negative of the coefficient of x term divided by the coefficient of x² term. The product ...
Equal roots occur when the discriminant (b² – 4ac) equals zero in a quadratic equation. This makes both roots identical meaning the parabola touches the x-axis at exactly one point. The value of both roots can be found using -b/2a ...
