Answer:
A) (4, -2)
Step-by-step explanation:
Answer:
-cos^4(x)
Step-by-step explanation:
Step 1: Use the Pythagorean identity : 1=cos^2(x) + sin^2(x)
1-sin^2(x) = cos^2(x)
-1+sin^2(x) = -cos^2(x)
cos^2(x) (-cos^2(x))
Step 2: Factor out common terms cos^2(x)
cos^2(x) (sin^2(x)-1)
Ans: -cos^4(x)
Answer:
a³-b³= (a-b)(a²+ab+ b²)

➷ First find two values that multiply to make 45 but add to make -14
As you will figure out through trial and error, it is -9 and -5
Factorize it with these values:
(g - 9)(g - 5)
The actual values for g would be the opposite of what is in the parenthesis
Therefore, g = 9, or g = 5
