Solve the equation y2 + 2y = 40, correct to 1 decimal place.
5 × 5 + (2 × 5) 25 + 10 = 35; too small y = 6 6 × 6 + (2 × 6) 36 + 12 = 48; too big So the answer lies between 5 and 6. y = 5.5 5.5 × 5.5 + (2 × 5.5) 30.25 + 11 = 41.25; too big y = 5.4 5.4 5.4 + (2 × 5.4) 29.16 + 10.8 = 39.96; too small So the answe
