Aquadratic equation is shown below:

25x2 + 10x + 1 = 0

part a: describe the solution(s) to the equation by just determining the radicand. show your work. (5 points)

part b: solve 4x2 − 4x + 1 = 0 by using an appropriate method. show the steps of your work, and explain why you chose the method used. (5 points)

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

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
