How do you write #y=x^2-3x-2# in vertex form?
1 Answer
Explanation:
Remember that that general vertex form is
with vertex at
Given
In this case we will ignore the
Completing the square
Rewriting as a squared binomial with a simplified constant
which is the vertex form with vertex at
Once more, here is the graph of the original equation for verification support:
graph{x^2-3x-2 [-3.524, 6.345, -4.77, 0.16]}
