Elena L [17]

The trinomial did she factor is \rm x^2-4x-12.

Given

Leonora is factoring a trinomial.

The factors of the trinomial are shown on the model.

<h3>Quadratic equation</h3>

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there.

Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

Algebra tiles are tiles used to represent variables or numbers and are rectangular or square-shaped.

1 is labeled + x squared, this gives x².

And 6 are labeled negative. 3 tiles are in the Factor 2 spot:

1 is labeled x and 2 are labeled. 0 tiles are in the Product spot.

-6x + 2x -12

Therefore

The trinomial did she factor is;

\rm x^2-4x-12

Hence, The trinomial did she factor is \rm x^2-4x-12.

More about the quadratic equation link is given below.

Use the permutation formula below to find the number of outcomes when n = 5 and r = 2.
faltersainse [42]

nPr =  \frac{n!}{(n - r)!}

5P2 =  \frac{5!}{(5 - 2)!}  =  \frac{5 \times 4 \times  3 \times 2 \times 1}{3 \times 2 \times 1}  = 20
