When solving the radical equation 2+2x+11−−−−−−√=x, the values x=−1 and x=7 are obtained. Determine if either of these values is a solution of the radical equation. Select the correct two answers. Since substituting x=−1 into the original equation resulted in a true statement, x=−1 is a solution to this equation.
Since substituting x=7 into the original equation resulted in a true statement, x=7 is a solution to this equation.
Since substituting x=7 into the original equation resulted in a false statement, x=7 is a not solution to this equation.
Since substituting x=−1 into the original equation resulted in a false statement, x=−1 is not a solution to this equation.
