SOLUTION: y=-(x+3)^2-4

Question 920724: y=-(x+3)^2-4

Answer by srinivas.g(540) (Show Source): You can put this solution on YOUR website!
y= -(x+3)^2 -4
y =-(x+3)*(x+3) -4
y = -(x(x+3)+3(x-3) -4
y = -(x^2+3x+3x+3*3)-4
y= -(x^2+6x+9)-4
y= -X^2-6x-9-4
y =-x^2-6x-13

Quadratic equation (in our case ) has the following solutons:

For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

The discriminant -16 is less than zero. That means that there are no solutions among real numbers.
