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

Answer:

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

Explanation:

As we have given an equation in the question  

Now we will solve this question with factor method as

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

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

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

So the correct options are D. And F.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
