Solve the equation by completing the square.

4x(x + 6) = -40

x = -6+-odmocnina36-40/2

Step-by-step explanation:

x=10

Step-by-step explanation:

10 times -4 is -40 since if you multiply a negative number by a positive you get a negative

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
