Emily realizes that the expression x^2+4x+3 can be written many equivalent ways. select all the expressions below that are equivalent.

Form 1:

For this case we have the following polynomial:

We want to write the polynomial in a different way.

We can, for example, factor the polynomial. We have then:

Factoring we have:

Therefore, an equivalent expression is given by:

Form 2:

We now write the equation in the form of vertex.

We have then:

Where,

(h, k): vertice of the parabola

Therefore, rewrite the equation we have:

Another equivalent form is the vertex form:

12.5 feet
