Hi Debbie, The point here is that you can only add quantities that have the same units.

A is the same in each equation, which is given as 10, and if we also plug in the vertex given we get (in vertex form). This equation can also be factored to the form:`y. A + b + c = 1 D.

Vertex form of parabola is y = a(x-h) 2 + k where (h,k) is the vertex. For any quadratic equation of the form y = ax 2 + bx + c, the quadratic formula below. Yes, we can find it using infinitesimals.

Then the equation a x 2 + b x + c = 0 ax^2+ bx + c = 0 a x 2 + b x + c = 0 is bound to have two roots since it is a quadratic equation. The velocity is the slope of the 1st equation. From the 2nd equation, we know that c=1.

Suppose you have ax 2 + bx + c = y, and you are told to plug zero in for y.The corresponding x-values are the x-intercepts of the graph. If you don't, you might use the wrong values for a, b, or c, and then the formula will give incorrect solutions. So solving ax 2 + bx + c = 0 for x means, among other things, that you are trying to find x-intercepts.Since there were two solutions for x 2 + 3x – 4 = 0, there must then be two x-intercepts on the graph.Graphing, we get the curve below:.
