What is the vertex of y=(x+2)(x-2)

If we write the quadratic equation in the vertex form, will be easy to find the vertex.

The vertex form of a quadratic function is:

Where the vertex is (h. k).

We have:

y=(x+2)(x-2)

Form this we conclude: a = 1, h = 0, k = -4. Then:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
