4 x 213 = 4 x (200 + 10 + 3) = 852
Answer: Option 'a' is correct.
Step-by-step explanation:
As we know about the discriminant value i.e.
if we have given a quadratic equation :
![ax^2+bx+c=0](https://tex.z-dn.net/?f=ax%5E2%2Bbx%2Bc%3D0)
then,
discriminant value will be
![b^2-4ac](https://tex.z-dn.net/?f=b%5E2-4ac)
There are 3 properties regarding discriminant value as follows:
![1)b^2-4ac>0\\\\means,\\\\\text{ there exists real zeros}\\\\2)b^2-4ac=0\\\\means,\\\\\text{ there exists equal zeroes}\\\\3)b^2-4ac](https://tex.z-dn.net/?f=1%29b%5E2-4ac%3E0%5C%5C%5C%5Cmeans%2C%5C%5C%5C%5C%5Ctext%7B%20there%20exists%20real%20zeros%7D%5C%5C%5C%5C2%29b%5E2-4ac%3D0%5C%5C%5C%5Cmeans%2C%5C%5C%5C%5C%5Ctext%7B%20there%20exists%20equal%20zeroes%7D%5C%5C%5C%5C3%29b%5E2-4ac%3C0%5C%5C%5C%5Cmeans%2C%5C%5C%5C%5C%5Ctext%7B%20there%20does%20not%20exists%20real%20zeroes%7D)
So, here we need a zero real number solutions i.e. there does not exists any real number.
So,
![b^2-4ac=-5](https://tex.z-dn.net/?f=b%5E2-4ac%3D-5)
Hence, Option'a' is correct.
'9' and '100' don't have any common factor except '1'.
So the fraction is already in lowest terms (simplest form).
It can't be reduced any further.
