## Chapter 8 | Important Concepts | RD Sharma Class 10 Solutions

• Quadratic equations are written in a simple format.

• Factorization, completing the square, and utilising the quadratic formula are all methods for obtaining their zeros or roots.

• Quadratic equations are used in a variety of scenarios in everyday life.

Example: Ashu is x years old, and his mother, Mrs Veena, is x2. MrsEasy Veena will be three times Ashu's age in five years. Determine their current ages.

Solutions:

Present age of Ashu = x years

and age of his mother = x² years

5 years hence,

age of Ashu will be = (x + 5) years

and age of his mother = (x² + 5) years

According to the question,

x² + 5 = 3 (x + 5)

⇒ x² + 5 = 3x + 15

⇒ x² + 5 – 3x – 15 = 0

⇒ x² – 3x – 10 = 0

⇒ x² – 5x + 2x – 10 = 0

⇒ x (x – 5) + 2 (x – 5) = 0

⇒ (x – 5) (x + 2) = 0

Either x – 5 = 0, then x = 5

or x + 2 = 0, then x = -2 which is not possible being negative

Present age of Ashu = 5 years

and age of his mother = x² = (5)² = 25 years
