what would be the approximation to the nearest ten-thousandth log 8900 over log 110?

Not sure where to go next. I need to solve this quadratic equation 7x^2-5=0. This is what I have so far, not sure where/what to do next x=2/7 x=sqrt2/7 or x=-sqrt2/7* =+/-sqrt2/7 +/-sqrt14/7 not even sure if this is right.

algebra-Am I right so far
Use the quadratic formula to determine the x-intercepts (if any)f(x)=2x^2=2 am I right so far? f(x)ax^2+bx+c y=ax^2+bx+c y=2x^2+2 y=0=>2x^2+2=0 =>2x^2+2=0 ax^2=2,bx=2,c=0 x=b=sqrtb^2+4ac over 2a x=(2)+sqrt(2)^24(2)(0)over2(2) x=sqrt4+4over 2

I am totally lost on how to solve g(x)=2x^2+3x-1 to find the y and x-intercepts. This is what I have so far, but I don't know if I am on the right track. And if so what would be next? g(x)=2x^2+3x-1 =2x^2+3x -1 =(2x^2+3+6) +3-1
