Answer:
-2( 7x+4)
Step-by-step explanation:
-14x - 8
Factor out -2
-2*7x -2*4
-2( 7x+4)
We will simplify the left hand side of the equation to look like the right
taking the LCM
expanding the binomial in the numerator
Since sin²x + cos²x = 1
factoring out the 2 from the numerator
1-sin(t) will cancel out
since cos²(t) = 1/(sec²(t))
which is equal to the right hand side of our given equation.
So we verified the identity!
