    you can shift the number 6 key to get the symbol for exponents

    I don't understand your previous comment. was it meant for me? did you delete mine about using the exponent symbol by mistake?

    let's review the complete question was not posted. I gave general information you can use for any polynomial. you posted the polynomial . I explained how to get the symbol for exponents. I solve the equation. you expressed that this is very new material and you need extra help. please review everything and let me know what questions you have so I can give you the help you need. You might want to takes notes for the general information you will need to know it later. I will check back in a few minutes if you have questions.

    the general format for the quadratic is ax^2 + bx + c = 0 here you have 3x^2 -x + 2 =0 when you compare them then you see that a = 3, b = -1 and c = 2 are you ok with this now?

    look at the first equation with a, b and c in it compare it with the second equation before the x^2 is a and the number before the x^2 is 3 therefore a = 3

    do the same with the x term bx = -x same as -1x the -1 is understood here b = -1
