Answer:
Step-by-step explanation:
To simplify this we factor the numerator and denominator separately
factor 4z^2 - 16z+15
We apply 'ac' method, 4* 15 = 60
-10 * -6 = 60
-10 - 6 = -16
Now we split -16z using factors -10z -6z
Take out GCf from first two terms and last two terms
(2z-3)(2z-5)
factor 2z^2 - 11z+15
We apply 'ac' method, 2* 15 = 30
-5 * -6 = 30
-5 - 6 = -11
Now we split -11z using factors -5z -6z
Take out GCf from first two terms and last two terms
(z-3)(2z-5)
Now we replace the factors
Cancel out 2z-5 at the top and bottom
The tangent ratio is an illustration of the trigonometry identity
The value of x that is not a solution of tan(x) = 1 is 3/4
The trigonometry identity is given as:
tan(x) = 1
Next, we test the x values using a calculator.
When , we have:
tan(-7/4) = 1
When x = 3/4, we have:
tan(3/4) = -1
When x = 5/4, we have:
tan(5/4) = 1
When x = /4, we have:
tan(/4) = 1
Hence, the value of x that is not a solution of tan(x) = 1 is 3/4
