the value of the discriminant of the quadratic equation
is
.
<u>Step-by-step explanation:</u>
Here we need to find What is the value of the discriminant of the quadratic equation -2x^2=-8x+8 or ,
.
We know that for a quadratic equation ,
, Discriminant is :
⇒ ![D = b^2-4ac](https://tex.z-dn.net/?f=D%20%3D%20b%5E2-4ac)
Now , let's frame equation
in form of
:
⇒
⇒ ![2x^2-8x+8=0](https://tex.z-dn.net/?f=2x%5E2-8x%2B8%3D0)
⇒ ![x^2-4x+4=0](https://tex.z-dn.net/?f=x%5E2-4x%2B4%3D0)
Comparing values we get that here , a=1 , b = -4 , c = 4 . Putting these values in
:
⇒ ![D = (-4)^2-4(1)(4)](https://tex.z-dn.net/?f=D%20%3D%20%28-4%29%5E2-4%281%29%284%29)
⇒ ![D =16-16](https://tex.z-dn.net/?f=D%20%3D16-16)
⇒ ![D =0](https://tex.z-dn.net/?f=D%20%3D0)
Therefore , the value of the discriminant of the quadratic equation
is
.
Step-by-step explanation:
go right 4
go down 3
it is the answer
![3 \times {7}^{4}](https://tex.z-dn.net/?f=3%20%5Ctimes%20%20%7B7%7D%5E%7B4%7D%20)
Because there's one 3 & four 7's .
![{2}^{2} \times {9}^{4}](https://tex.z-dn.net/?f=%7B2%7D%5E%7B2%7D%20%20%5Ctimes%20%20%7B9%7D%5E%7B4%7D%20)
Because there are two 2's & four 9's
Answer:
2^2×20
Step-by-step explanation:
2^2×20
because 2×20=40
so, 2^2×20=2^40
