10वीं कक्षा: द्विघात समीकरण और ज्यामिति

Study Notes

Quadratic Equations

Quadratic equations are solved using various methods, including the quadratic formula.
The solutions to a quadratic equation are found by using the formula: $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$
Examples of quadratic equations and their solutions are shown.
The discriminant (b² - 4ac) determines the nature of the roots (real, imaginary, repeated).

Geometry and Trigonometry

Problems involve angles and relationships within triangles
Specific examples show calculation of sides and angles using trigonometric functions (sin, cos, tan, etc.)
The Pythagorean theorem may be used to find missing sides of right-angled triangles
Given sides and angles, trigonometric calculations can be conducted.

Coordinate Geometry

Coordinate points are identified for triangle vertices (A, B, C).
Formulas and calculations relating to distances between points are utilized (distance formula).
Perimeters and areas of shapes are found using relevant formulas.

Algebraic Equations (Various)

Different examples demonstrate solving algebraic equations.
Several examples are shown of expanding expressions, grouping terms, and solving for unknown variables

Advanced Algebraic Equations

More complex equations are addressed
