74 words per minute
Step-by-step explanation:
If the tiles
3478 words ———————-> 47 mins
? Words ————————> 1 min
cross multiply
?=74
Then there are two real roots
Here we have D > 0 i.e Discriminant = 18
Hence, There are two real roots.
Step-by-step explanation:
Given:
To Find :
Which statement describes the roots form all Four options = ?
Solution:
For a Quadratic Equation:
The Discriminant is given as,
So if this Discriminant, say D,
Case 1 :
Then there are two real roots
Here we have D > 0 i.e Discriminant = 18
Hence, There are two real roots.
Case 2 :
If,
Then there are two complex roots.
Case 3 :
If,
Then there are Same and Real roots.
