Question

Solve 3x2 − 5x + 7 = 0. x equals the quantity of negative 5 plus or minus square root 109 all over 6 x equals the quantity of 5 plus or minus square root 109 all over 6 x equals the quantity of negative 5 plus or minus i square root 59 all over 6 x equals the quantity of 5 plus or minus i square root 59 all over 6

Answer 1

Solve:

3x^2 - 5x + 7 = 0

Answer : x = 5/6 + i sqrt 59/6, x = 5/6 + i sqrt 59/6

Solve the Equation:

3x^2 - 5x + 7 = 0

Step 1: Use quadratic Formula with a = 3, b = -5, c = 7:

x = -b +/- sqrt b^2 - 4ac/ 2a

x = - ( - 5) +/- sqrt ( - 5)^2 - 4(3)(7)/ 2(3)

x = 5 +/- sqrt - 59/6, which will become, x = 5 +/- sqrt i 59/6, x = 5 +/- sqrt i 59/6

No Real Solutions:

Your answer would be, Letter Choice, (D), x equals the quantity of plus, or minus i sqrt 59 all over 6. Hence, No Real Solutions
