Answer:
Step-by-step explanation:
For many of these identities, it is helpful to convert everything to sine and cosine, see what cancels, and then work to build out to something. If you have options that you're building toward, aim toward one of them.
and
Recall the following reciprocal identity:
So, the original expression can be written in terms of only sines and cosines:
Working toward one of the answers provided, this is the tangent function.
The one caveat is that the original expression also was undefined for values of beta that caused the sine function to be zero, whereas this simplified function is only undefined for values of beta where the cosine is equal to zero. However, the questions states that we are only considering values for which the original expression is defined, so, excluding those values of beta, the original expression is equivalent to .
2x+5y=20
X=10-2.5y
-2(10-2.5y)+20y=-90
-20+5y+20y=-90
25y=-70
Y=2.8
2(2.8)+5y=20
5.6+5y=20
5y=14.4
Y=2.88
CHECK:
2(2.8)+5(2.88)=20
X=10-2.5y
-2(10-2.5y)+20y=-90
-20+5y+20y=-90
25y=-70
Y=2.8
2(2.8)+5y=20
5.6+5y=20
5y=14.4
Y=2.88
CHECK:
2(2.8)+5(2.88)=20
is one of the prime factors of the polynomial
The question implies that we determine one of the prime factors of the polynomial.
The polynomial is given as:
Expand the polynomial by adding 0's in the form of +a - a
Rearrange the terms
Factorize the expression
Factor out x^6-2x^5+2x^3-3x^2+2x-1
Express x^2 + 2x + 1 as a perfect square
Expand the polynomial by adding 0's in the form of +a - a
Rearrange the terms
Factorize the expression
Factor out x^3-2x^2+x-1
One of the factors of the above polynomial is .
This is the same as the option (c)
Hence, is one of the prime factors of the polynomial
