Solve the following equations by using quadratic formula and give answer in correct to 2 decimal places : (i) 4x2 - 5x - 3 = 0 (ii) x2 - 7x + 3 = 0

(i) The given equation is 4x2 - 5x - 3 = 0 Comparing it with ax2 + bx + c = 0, we get a = 4 , b = -5 , c = -3 By using formula, we obtain: Hence roots of the given equations are 1.69, -0.44. (ii) For a quadratic equation in the form : ax2 + bx + c = 0 The solutions are : x = Comparing equation x2 - 7x + 3 = 0, with ax2 + bx + c = 0, we get : a = 1, b = -7 and c = 3 Hence, the value of x = 6.54 or 0.46
