George was solving the equation $(2x-1)(x+3)=4$ and he got the solutions $x=\frac { 1 } { 2 }$ and $x = -3$. Jeffrey came along and said, “You made a big mistake! You set each factor equal to zero, but it’s not equal to zero, it’s equal to $4$. So you have to set each factor equal to $4$ and then solve.” Who is correct? Show George and Jeffrey how to solve this equation. To be sure that you are correct, check your solutions. Homework Help ✎
