Question:

Use the quadratic formula to find the solutions to the quadratic equation below. Check all that apply. 4x^2-x-5=0.

A.1

B. 3/2

C -4/5  

D 5/4

E 2/3

F -1

<u>Answer</u>:

The correct options are D.  5/4  and F -1

<u>Explanation</u>:

As we have given an equation in the question  

4x^2-x-5=0

Now we will solve this question with factor method as

4x^2-x-5=0

Now we can write -x as 4x-5x in the given equation  

4x^2+4x-5x-5=0

Now we take terms common from first two terms and last two terms  

4x(x+1)-5(x+1)=0

(4x-5)(x+1)=0

Now the above equation will be equal to zero if x= -1 or x=5/4

So the correct options are D. And F.
