RD Sharma Class 11 Maths Solutions Chapter 14 - Quadratic Equations

Q: 6. What should be the first step if a problem in RD Sharma doesn't look like the standard ax² + bx + c = 0 form?

If an equation is not in the standard quadratic form, the first and most important step is to simplify and rearrange it. This might involve expanding brackets, moving all terms to one side of the equation, and combining like terms until it clearly matches the ax² + bx + c = 0 structure. Only then can you correctly identify the coefficients a, b, and c to solve it.

Q: 7. How do I decide whether to use factorization or the quadratic formula to solve a problem?

A good approach is to first try the factorization method. If you can quickly see how to split the middle term, it's often faster. However, if the coefficients are large or you cannot find the factors easily, it's more efficient to use the quadratic formula. The formula is a universal tool that works for every quadratic equation.

What is a Quadratic Equation?

Quadratic equations are two-variable polynomial equations of the kind f(x) = ax²+ bx + c, where a, b, c, R, and an are all zero. It is the generic form of a quadratic equation in which the leading coefficient is 'a' and the absolute term of f is 'c' (x). The roots of the quadratic equation (,) are the values of x that fulfill the quadratic equation.

There will always be two roots to a quadratic equation. Roots can have either a true or fictitious nature.

When you equal a quadratic polynomial to zero, you get a quadratic equation. The roots of the quadratic equation are the values of x that satisfy the equation.

3. What are the main methods for solving quadratic equations covered in RD Sharma Chapter 14?

The chapter on Quadratic Equations in the RD Sharma textbook primarily covers three main methods to find the roots of an equation:

Factorization: Splitting the middle term to find the factors.
Quadratic Formula: Using the formula x = [-b ± √(b²-4ac)] / 2a to find the roots directly.
Completing the Square: Transforming the equation into a perfect square.

4. Are the solutions for RD Sharma Class 11 Maths Chapter 14 aligned with the CBSE syllabus?

Yes, our solutions for RD Sharma's Quadratic Equations chapter are fully aligned with the CBSE Class 11 Maths syllabus for the 2025-26 academic year. They cover all essential topics, including the quadratic formula, the nature of roots based on the discriminant, and the relationship between roots and coefficients.

5. How does the discriminant (b² - 4ac) actually determine if the roots of a quadratic equation are real or imaginary?

The discriminant is the part of the quadratic formula that is under the square root sign. Its value tells you about the roots without solving the full equation.

If b² - 4ac > 0, you are taking the square root of a positive number, which gives two distinct real roots.
If b² - 4ac = 0, the square root term becomes zero, resulting in two equal real roots.
If b² - 4ac < 0, you would be taking the square root of a negative number, which results in two complex (or imaginary) roots.

6. What should be the first step if a problem in RD Sharma doesn't look like the standard ax² + bx + c = 0 form?

If an equation is not in the standard quadratic form, the first and most important step is to simplify and rearrange it. This might involve expanding brackets, moving all terms to one side of the equation, and combining like terms until it clearly matches the ax² + bx + c = 0 structure. Only then can you correctly identify the coefficients a, b, and c to solve it.
