The common difference in an arithmetic progression (A.P.) is the constant value added to each term to get the next term. It represents the fixed increase or decrease between consecutive terms in the sequence and remains unchanged throughout the progression. An ...

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 ...
A quadratic equation has the standard form ax² + bx + c = 0 where a b and c are numbers and a is not equal to 0. We can solve it using the quadratic formula -b ± √(b² – ...
An equation shows that two mathematical expressions have the same value using an equals sign (=). It can involve numbers variables functions and mathematical operations to express relationships. Equations help us solve problems find unknown values and describe mathematical patterns ...
The quadratic formula solves ax² + bx + c = 0 where a b and c are numbers and a ≠ 0. The solution is x = [-b ± √(b² – 4ac)] / (2a). The ± means to calculate both ...
A root is a part of the plant that grows underground and absorbs water and nutrients from soil. It anchors the plant firmly and stores food. Roots can be thin or thick fibrous or taproots spreading deep in soil and ...
Equal roots occur in a quadratic equation when the discriminant equals zero. This means both roots have the same value indicating the parabola touches the x-axis at exactly one point. For example x² + 4x + 4 = 0 has ...
