Aquadratic equation is shown below:

9x2 − 16x + 60 = 0

describe the solution(s) to the equation by just determining the radicand. show your work.

: solve 4x2 + 8x − 5 = 0 by using an appropriate method. show the steps of your work, and explain why you chose the method used.

hello : 

help :
the discriminat of each quadratic equation : ax²+bx+c=0 (a ≠ 0) is :
Δ = b² -4ac
1 )  Δ > 0  the equation has two reals solutions : x =  (-b±√Δ)/2a
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ < 0 : no reals solutions

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
