How do i solve qudratic equations with factions, like this one: x²-5= 0

There are several approaches.

(5/3)x^2 - 5 = 0 has the coefficients a=5/3, b=0 and c = -5.

Thus, the quadratic formula would be appropriate here:

         -0 plus or minus sqrt(0^2 - 4(5/3)(-5) )
x  =
                                 2(5/3)
         plus or minus sqrt(100/3)
    =
                         10/3
            3      10
     = * = sqrt(3)    (answer)
          10     sqrt(3)

Do the math. she originally had 50 dollars on her gift card and she had 12 dollars left on her gift card after she finished her shopping spree. if you subtract 50 minus 12 you get thirty eight dollars as your answer. so therefore, ciara spent 38 dollars total o
