Weegy: The general form of the equation 5x^2 - 20x = 15 is 5x^2 - 20x - 15 = 0.
User: The line of symmetry of the parabola whose equation is y = ax2 - 4x + 3 is x = -2. What is the value of "a"?
User: Describe the translation of the graph of y = x2 that results in the graph of y = (x - 3)2.

(x + 3)(x + 4) = 5 is quadratic.
(x + 3)(x + 4) = 5
x^2 + 3x + 4x + 12 = 5
x^2 + 7x + 7 = 0

The line of symmetry of the parabola whose equation is y = ax^2 - 4x + 3 is x = -2. -1 is the value of "a".
4/2a = -2
4 = -4a
a = -1

3 units right is the translation of the graph of y = x^2 that results in the graph of y = (x - 3)^2.
