Answer

$(-\infty, 0)$

Work Step by Step

Graph $y_1 =(x+1)^2$ (the orange graph) and $y_2=(x-1)^2$ (the purple graph) on the same coordinate plane. (refer to the attached image below for the graph) The solution to the given inequality is the set of x-values for which $y_1 \lt y_2$. Notice that $y_1$ (the orange graph) is less than $y_2$ for x values to the left of $0$. Thus, the solution to the given inequality is: $(-\infty, 0)$
