Question

can anyone tell me how i can check the behavior of the equation?

Answer 1

which equation?

Answer 2

quadratic equation

Answer 3

Positive leading coefficient for example
2x^2 + 5x + 3, the graph opens upward.
Negative leading coefficient:
-2x^2 + 5x + 3, the graph opens downward.

Answer 4

What kind of behaviour? End behaviour?

Answer 5

If it was end behavior that is.

Answer 6

b-4ac?

Answer 7

You could also hire a babysitter, or use a nannycam to check it's behaviour.

Answer 8

b-4(a)(c) is not a quadratic, it is part of the quadratic formula.

Answer 9

well sqrt of that is part of the quadratic formula.

Answer 10

can i check behavior of equation with thi formula?

Answer 11

sqrt(b^2-4ac) is actually.

Answer 12

quadratic equations don't need babysitters. they are nice and well-behaved.

Answer 13

@shamil98 thanks

Answer 14

lol @richyw :D

b^2-4ac is the discriminant of a quadratic.

If b^2-4ac > 0 then the quad. equation has two real solutions/zeroes/x intercepts

If b^2-4ac = 0 then the quad. equation has one solution/zero/x intercept

If b^2-4ac < 0 then the quad. equation has two imaginary solutions/zeroes/x intercepts

Answer 15

thanks i was looking for this.......
