Let's simplify the equation step by step:
Expand the left side of the equation:(х+1)^2 = x^2 + 2x + 1
Expand the right side of the equation:(1-x^2)/2 = (1/2) - (x^2/2)
Rewrite the equation with the expanded terms:x^2 + 2x + 1 - (1/2) + (x^2/2) = 4
Combine like terms:x^2 + x + (2/2) - (1/2) = 4x^2 + x + 1/2 = 4
Subtract 1/2 from both sides of the equation:x^2 + x = 4 - 1/2x^2 + x = 7/2
Therefore, the simplified form of the equation is x^2 + x = 7/2.
