Answer:
Step-by-step explanation:
Next time, please share the possible answer choices.
a^2 - b^2 is "a difference with two terms."
So is x - y.
Given:
Polynomial 
To find:
The values of x.
Solution:
Quadratic equation formula:
Here 
.
Substitute the values in the formula, we get
Option E and option F are the roots of the polynomial.
The values of x are 
.
Hello,
1. Since Angle C has the longest side for this triangle, it will have the largest degree value.
2. Use the Law of Cosines and inverse properties of “theta” to solve for Angle C. (Ensure that the calculator used is in “degree mode”, not “radian mode”.
c^2 = a^2 + b^2 - 2(a)(b)(cos (C))
15^2 = 11^2 + 14^2 - 2(11)(14)(cos(C))
225 - 317 = -2(11)(14)(cos(C))
-92 / -2(11)(14) = cos(C)
cos(C) becomes ->> cos^-1[92 /-2(11)(14)] = 72.62° ->> to the nearest degree is 73°
The answer for angle C, 73°, is logical because the triangle in the picture represents a 60-60-60 triangle, known as an equilateral triangle.
Good luck to you!
The answer for x should be X= -9
