Final answer:
To solve the equation 136 + x × x + 56, we need to follow the order of operations (PEMDAS/BODMAS). The equation does not have a real solution as √-192 is not a real number.
Step-by-step explanation:
To solve the equation 136 + x × x + 56, we need to follow the order of operations (PEMDAS/BODMAS). First, perform the multiplication: x × x = x^2. The equation becomes 136 + x^2 + 56. Combine like terms: 136 + 56 = 192. The equation is now x^2 + 192. To isolate x, subtract 192 from both sides: x^2 = -192. Take the square root of both sides: x = ±√-192. As √-192 is not a real number, the equation does not have a real solution.
