I. a3 - 988 = 343, II. b2 - 72 = 49 to solve both the equations to find the values of a and b?
Correct answer: B. If a ≥ b
- A. If a > b
- B. If a ≥ b
- C. If a < b
- D. If a ≤ b
Explanation
Interpreting a3 as a³, a³ - 988 = 343 gives a³ = 1331, so a = 11. Also, b² - 72 = 49 gives b² = 121, so b = 11 or -11; therefore a ≥ b in both cases. The likely trap is a > b, which ignores the valid case b = 11 where the two values are equal.

About Quadratic Equations
Quadratic equations contain a squared variable and can be solved by factorisation, completing the square, the quadratic formula, or graphical reasoning. Questions cover roots, the discriminant, and the relationship between roots and coefficients, while distinguishing real and repeated roots from complex or non-real roots.
