In which form is the following function written? y = - 2(x – 3)(x + 5)

The diagonals of a quadrilaretral intersect at (-1,4). one of the sides of the quadrilateral is bounded by (2,7) and (-3,5) determine the coordinates of the other side in order for the quadrilaretral to be a square.

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12
