I need to solve for x in these two question;

x: -3x2 + 4x = 4

x: x2 + 3x + 4 = 0

I'm quite sure there will be two awnsers for each question

I tried plugging in the numbers into this formula -b+/- sqrt> b^2 -4(a)(c)/2a

i need somebodies help because my arithmatic is bad, and i cant seem to get a whole number as my awnser so im stuck
