9x²-18x+14=0 quadratic equation

x∉R

Step-by-step explanation:

1) Solve the quadratic equation 9x²-18x+14=0 using x = (-b±√b²-4ac) / 2a:

x = ( - (-18) ±√ (-18) ²-4*9*14) / 2*9

2) Evaluate the power, calculate the product and multiply the numbers:

x = (18±√324-504) / 18

3) Calculate the difference:

x = (18±√-180) / 18

4) The square root of a negative number does not exist in the set of Real Numbers:
