Answer:
The answer is:
which agrees with the last answer option (D) in the list.
Step-by-step explanation:
In order to add rational expressions, we need to express them with the same denominator. Therefore we examine what factors there are in the first denominator, which happens to be a difference of squares which is readily factored out as:
the second denominator consists of only one of these factors: , then in order to express both rational expressions with the same common denominator, we multiply numerator and denominator of the second fraction by the factor:
Then we get two expressions that can be easily added as shown below:
The trinomial did she factor is .
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;
Hence, The trinomial did she factor is .
