Best ResponseYou've already chosen the best response.1If you're solving for x then the quadratic formula would be of better use:\[x=\frac{b\pm\sqrt{b^{2}4ac}}{2a}\]

Best ResponseYou've already chosen the best response.0Find the value of the discriminant for each quadratic equation below. Show all steps needed to write the answer in simplest form, including substituting the values of a, b, and c in the discriminant formula. Then use the value to determine how many real number solutions each equation has.

Best ResponseYou've already chosen the best response.0a = 5, b = 1, c = 4 D = 1  4(5)(4) D = 81. is it correct?

Best ResponseYou've already chosen the best response.21st u need to convert the equation into this form\[ax^2+bx+c=0\]so there shuld be a 0 on the left hand side can u bring a zero out there by subtracting 4 from both sides :)
