SUMMARY

The discussion centers on solving the quadratic equation 3x² - 4x + 2 = 0 using the quadratic formula. The correct application of the formula yields complex roots: x = 2 - 2√2i and x = 2 + 2√2i. A key takeaway is the importance of using parentheses in mathematical expressions to ensure accurate calculations. The initial attempt at simplification was flawed due to the lack of proper grouping in the equation.

Homework Statement


find the roots of:
3x^2 − 4x + 2 = 0

Homework Equations


quadratic equation


The Attempt at a Solution


4+/- sqrt16-24/6

4+/-sqrt-8/6

4+/- isqrt4 sqrt2

4+/-2isqrt2/6
simplify a bit

x= 2-2sqrt2i
x= 2+2sqrt2i

does this seem right?

When you're typing mathematical expressions on a single line, you need to use parentheses to group things appropriately.

For your equation, 3x^2 -4x + 2 = 0 (a quadratic equation), you can use the quadratic formula:
x = (-b [tex]\pm[/tex] [tex]\sqrt{b^2 - 4*a*c}[/tex])/(2*a).

Without the LaTeX coding, this can be written as

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

What you have in your first line after applying the quadratic formula is this:
4+/- sqrt16-24/6

If you had used parentheses, you would have had a better chance of getting the right answer. How about giving them a try?
