Solve the following quadratic equations by completing the square method.
(1) x2 + x – 20 = 0 Solution: (2) x2 + 2x – 5 = 0 Solution: (3) m2 – 5m = -3 Solution: (4) 9y2 – 12y + 2 = 0 Solution: Given 9y2 – 12y + 2 = 0 The above equation can be written as (3y)2 – 2 × 3y × 4 + (4)2 – (4)2 + 2 = 0 (3y)2 – […]
