(a + b) (a-b ) - 4b - 4
<u>Explanation:</u>
Given:
a² - b² - 4b - 4
(a + b) (a-b ) - 4b - 4
This equation cannot be solved further.
Thus, the equation is (a + b) (a-b ) - 4b - 4
Divide both sides by negative two
the answer is x = -1
To simplify the expression given <span>sinx+cosx/sinxcosx, the first step to do is to divide each term of the numerator to the denominator. In this case, the resulting expression is 1/cos x + 1/ sin x. These terms are inverse trigonometric identities. The answer is sec x + csc x. </span>
(3 * n) +4 = 16
(3 * n) = 12
n = 4
