Hi

Re: Standard form ax^2 + bx + c = 0, discriminant is b^2 - 4ac

discriminant of the equation 

5x^2-3x=8 

5x^2-3x- 8 = 0      |in standard form

 b^2 - 4ac

 3^2 - 4*(-40) = 9 + 160 = 169

Note: quadratic formula for solving this equation:

 

x+=+%283+%2B-+13%29%2F%2810%29+ 

   x = 1.6   x = -1
