(-2x + 10y)(4x - 6y)

Use FOIL.

-2x*4x = -8x^2
10y*-6y = -60y^2
10y*4x = 40xy
-2x*-6y = 12xy

Combine the like terms (the ones that have been bolded).
40xy + 12xy = 52xy

Put all the variables together.

(-2x + 10y)(4x - 6y) =
-2x(4x - 6y) + 10y(4x - 6y) =
-8x^2 + 12xy + 40xy - 60y^2 =
-8x^2 + 52xy - 60y^2 <==

Which statement is not true about the parabola?
pantera1 [17]

Answer:

D: The maximum value is 0

Step-by-step explanation:

Choice A is true because the x-intercepts are shown on the graph and are both -2 and 2.

Choice B is true because the parabola intercepts the y axis at 2.

Choice C is true because the AoS runs down the vertex which happens to be on the point (0,2).

Choice D is false because this parabola has no maximum value (parabolas continue forever unless stated otherwise).
