To find the solutions of the equation (2x^2 + 8x + 26 = 0), we can use the quadratic formula (x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}), where (a = 2), (b = 8), and (c = 26). First, we calculate the discriminant: (b^2 - 4ac = 8^2 - 4(2)(26) = 64 - 208 = -144). Since the discriminant is negative, the equation has no real solutions, but two complex solutions given by (x = -4 \pm 6i).

How many solutions are there to the equation below 8x plus 11 8x plus 8?
To find the number of solutions to the equation (8x + 11 = 8x + 8), we can simplify it by subtracting (8x) from both sides, resulting in (11 = 8). This is a false statement, indicating that there are no values of (x) that can satisfy the equation. Therefore, there are zero solutions to this equation.
