How do you write y=1.4x^2+5.6x+3 in vertex form?
1 Answer
Explanation:
To find the
To find the y coordinate of the vertex, plug
The vertex is
Use the formula for the vertex form of a quadratic.
To find the constant
Thus, a point that satisfies the equation is
Use this point to find
Substituting
There is another process for converting standard form to vertex form called completing the square. If you need to learn this method, please comment, and I will add it to the answer.
