1] α = 3/10 β = 4/15 We know that:- k(x² + (α+β)x - αβ) x² + (3/10 + 4/15)x - 3/10 * 4/15 x² + (17/30)x - 2/25 LCM = 50 (50x² + 85/50x - 4/50)/50 = 0 -> Hence, the required polynomial is 50x² + 85x - 4

Aashika Bi 2 years, 6 months ago

Let 1/√2 be a rational number So 1/√2= p/q where p and q are co primes and q≠0 q/√2=p Squaring on both sides, q²/2=p² —(1) Here, q² is divisible by 2 so q is also divisible by 2 Let q=k Put value of q in equation (1) k²/2=p² Divide by 2 on both sides k²/4=p²/2 Here, p² is divisible by 2 so p is also divisible by 2 But we have assumed that p and q are co primes This contradiction has arisen due to our wrong assumption Hence 1/√2 is an irrational number
