Answer:
(2v +7)(v -9)
Step-by-step explanation:
Factors of 2·(-63) = -126 that have a sum of -11 are 7 and -18, so we can rewrite the middle term to -18v+7v. Then we can factor by grouping.
2v^2 -18v +7v -63 = 2v(v -9) +7(v -9)
= (2v +7)(v -9)

The identified for the construction is the endpoint of rays BA and BC option (C) is correct.
<h3>What is an angle?</h3>
When two lines or rays converge at the same point, the measurement between them is called a "Angle."
It is given that:
Angle ABC has point E on ray BA and point D on ray BC.
Points E and D are equidistant from point B.
The ED distance because if the distance between E and D is even slightly different, the entire angle ABC will vary.
Thus, the identified for the construction is the endpoint of rays BA and BC option (C) is correct.
