Part D. Below are the steps Sean used to solve for the value of x. How would you respond to Sean? Include in your response whether or not Sean made a mistake, what the mistake is, why this step will not work, and then
model the correct solution process for Sean.
Step 1: 2x²+x-10=0
Step 2:2r? +x= 10
Sean added 10 to both sides of the equation.
Step 3: x(2x + 1) = 10
Sean factored the quadratic expression.
Step 4: x= 10 and 2x + 1 = 10
Sean set each factor equal to 10.
Step 5: x= 10 and x =
Sean solved each equation for x.

Luke started a weight-loss program. the first week, he lost x pounds. the second week, he lost pounds less than times the pounds he lost the first week. the third week, he lost 1 pound more than of the pounds he lost the first week. liam started a weight-loss program when luke did. the first week, he lost 1 pound less than times the pounds luke lost the first week. the second week, he lost 4 pounds less than times the pounds luke lost the first week. the third week, he lost pound more than times the pounds luke lost the first week.
