Use the discriminant to determine the nature of the roots of the following equation.
1 answer:
Discussion
The discriminate is b^2 - 4*a*c
The general equation for a quadratic is ax^2 + bx + c
In this equation's case
a = 1
b= -5
c = - 3
Solve
(-5)^2 - 4*(1)*(-3)
25 - (-12)
25 + 12
37
Note
Since the discriminate is > 0, the roots are real and different. The roots do exist and there are 2 of them.

I think it would be a measuring cup. hope i helped
Try this option:
or -2ctg²x
1/2 = 4/8
3 5/8 - 2 4/8 = 1 1/8 yards left over
the answer would be4.7^-10^4
Both equations are equivalent, so there are infinitely many solutions.
