Question 69

Multiple Choice

Solve the equation x24x3=0x ^ { 2 } - 4 x - 3 = 0 by completing the square. Give the solutions in exact form and in decimal form rounded to two decimal places. (The solutions may be complex numbers.)


A) 4+7i4+2.65i4 + \sqrt { 7 } i \approx 4 + 2.65 i ; 47i42.65i4 - \sqrt { 7 } i \approx 4 - 2.65 i
B) 2+7i2+2.65i2 + \sqrt { 7 } i \approx 2 + 2.65 i ; 27i22.65i2 - \sqrt { 7 } i \approx 2 - 2.65 i
C) 4+76.654 + \sqrt { 7 } \approx 6.65 ; 471.354 - \sqrt { 7 } \approx 1.35
D) 2+74.652 + \sqrt { 7 } \approx 4.65 ; 270.652 - \sqrt { 7 } \approx - 0.65
E) 2+70.65- 2 + \sqrt { 7 } \approx 0.65 ; 274.65- 2 - \sqrt { 7 } \approx - 4.65
