Question 24 Find the nature of roots of the quadratic equation š‘„^2 + 4š’™ āˆ’3āˆš2=0. x2 + 4x ā€“ 3āˆš2 = 0 Comparing equation with ax2 + bx + c = 0 a = 1, b = 4, c = ā€“3āˆššŸ We know that D = b2 ā€“ 4ac D = šŸ’^šŸāˆ’šŸ’ Ɨ šŸ Ɨ (āˆ’šŸ‘āˆššŸ) D = 16+4 Ɨ 3āˆš2 D = šŸšŸ”+šŸšŸāˆššŸ Concept: D < 0 , no real roots D = O , two equal real roots D > 0, two distinct real roots Since both numbers are adding, it will always be positive (i.e. D > 0) Since D > 0 The given equation has two distinct real roots
