Write a quadratic equation given the x intercepts and one other point. Step 2: Find a. Now that you know that the factors are (x-6) and (x-8), you must find a. Plug the coordinates of the vertex (7, 1) in for x and y and solve for a. y = a(x-6)(x-8) What is the value of a?
a = 1
a = -1
a = 7
a = -7

Write a quadratic equation given the x intercepts and one other point.
Put the steps together.
- Find the factors.
- Solve for a by substituting in the extra point.
- Write the equation in factored form.
The roots of the function are (-3, 0) and (5, 0).
The point (4, -3) is also on the graph.
y=4(x+3)(x-5)
y=3/7(x-3)(x+5)
y=-3(x-3)(x+5)
y=3/7(x+3)(x-5)

Write a quadratic equation in vertex form given the vertex and another point.
- Substitute the coordinates of the vertex (1, -4) in for h and k.
Vertex form: y=a(x-h)2+k
(x+1)2-4=y
(x-1)2-4=y
(x + 1)(x - 3)=y
x2 +2x - 3=y
