To solve the equation 8sin(x)cos(x) + 4 = 0, first, we need to factor out a common term. We can factor out 4 from the equation, leaving us with 4(2sin(x)cos(x) + 1) = 0. Next, we solve each factor separately. Setting 4 = 0 gives no solution. Solving 2sin(x)cos(x) + 1 = 0 involves solving the trigonometric equation. We can rearrange it to get sin(x)cos(x) = -1/2. This can be solved using trigonometric identities or graphically, yielding multiple solutions for x, typically in the form of x = π/3 + nπ or x = 2π/3 + nπ, where n is an integer.
