Q1Multiple choiceExercise 4.3
Find the roots of the quadratic equations by using the quadratic formula in each of the following:
- (i)2x2 – 3x – 5 = 0
- (ii)5x2 + 13x + 8 = 0
- (iii)–3x2 + 5x + 12 = 0
- (iv)–x2 + 7x – 10 = 0 (v) x2 + 2 2 x – 6 = 0 (vi) x2 – 3 5 x + 10 = 0
Show answer
(i) 2x2 – 3x – 5 = 0
(ii) 5x2 + 13x + 8 = 0
(iii) –3x2 + 5x + 12 = 0
(iv) –x2 + 7x – 10 = 0 (v) x2 + 2 2 x – 6 = 0 (vi) x2 – 3 5 x + 10 = 0
