Rewrite the quadratic function in intercept or factored form f(x)=9x^2-4

Step-by-step explanation:

To solve the exercise you must apply the proccedure shown below:

1. You can rewrite the following terms:

2. Both are perfect squares, therefore, by the difference of squares:

3. Then, you can rewrite the quadratic equation as it is shown below:

y = i/2 xtnop + (3i/2 tnop+ 1)
