Quadratic equation
The discriminant is the part of the quadratic formula within the square root symbol: . The discriminant indicates if there are two solutions, one solution, or none.
The discriminant can be positive, zero or negative which determines how roots exist for the given quadratic equation.
So, a positive discriminant tell us that the quadratic has two different real solutions.
A discriminant of zero tell us that the quadratic has two real and equal solutions.
And a negative discriminant tell us that none of the solutions are real numbers.
In this case: 25x^2-10x+1=0
We can see that
a= 25 b=-10 c=1
Using:
We have
the answer is zero, so the quadratic has two real and equal solutions
Hi there!
To make n+1>4 true, you must have n be a numebr greater than 3...
The reason why is because if it is less than 3 or 3, it’ll have to be <.
The two numbers that can make this equation true is 4 and 5...
And if it is 1,2, and 3 it would be:
This is a geometric sequence with n th term formula
=
where r is the common ratio and the first term
here = -
and
r = =
= 6
= -
or in terms of x
f(x) = -
