So firstly, foil 3(4g + 6) and 2 (6g + 9):
Now since the quantity is the same on both sides of this equation, this means that <u>this equation has infinite solutions.</u>
if the diagonals of a quadrilateral biscects each other, then the quadrilateral is a parallelogram. true or false

so, this is a quadratic equation, meaning two solutions, and we have a factored form of it, meaning you can get the solutions by simply zeroing out the f(x).
so the zeros/solutions are at x = 3 and x = -11, now, bearing in mind the vertex will be half-way between those two, checking the number line, that midpoint will be at x = -4, so the vertex is right there, well, what's f(x) when x = -4?
