Richiez: Question 4 ...still by Quiz master Doubledx Solution ============================ The roots of the equation x2 + Qx + 24 = 0 are α and β x2 + Qx + 24 = 0 ....eqn(1) Then, x = α or x = β To form the equation (x - α)(x - β) = 0 x2 - xβ - xα + αβ = 0 x2 - x(α + β) + αβ = 0 .....eqn (2) x2 + Qx + 24 = 0 .....eqn (1) Comparing equations (1) & (2), the coefficient of x can be equated as follows. Qx = - x (α + β) (α + β) = -Q ...eqn(3) Equating the constants αβ = 24 .....eqn(4) We know that => α2 + β2 = 73 = (α + β)2 - 2αβ (α + β)2 - 2αβ = 73 ....eqn(5) Now, substitute the values of (α + β)....eqn(3) and αβ...eqn (4) in eqn(5). (α + β)2 - 2αβ = 73 (-Q)2 - 2(24) = 73 Q2 - 48 = 73 Q2 = 73 + 48 Q2 = 121 Q = ±√121 Q = ±11 Hence the equation becomes => x2 + 11x + 24 = 0 or x2 - 11x + 24 = 0 Which after factoring yields=> x = -3 and x = -8, and also for the second equation x = 3 or 8 Thus => Statement 1 is true for both equations. Statement 2 is true for the first equation. Statement 3 cannot be true for any of the equations. Hence, the answer is 1 and 2. Anyone who chooses any of 1 and 2 is correct! |
