Jason writes an expression equivalent to -2 +5(d + 1) - 6d his work is shown below -2 +5(d + 1) - 6d
Step 1: 3(d + 1) - 6d
Step 2: 3d + 3 - 6d
Step 3: (3 - 6)d + 3
Step 4: -3d + 3
In what step does jason first make an error, and what is his error?
Filli in the blanks
Jason made an error step in 1, 2, 3, or 4. The best description of the error is that he should have distributed before adding, distributed incorrectly, should have factored d from all terms, combined terms incorrectly. The correct equivalent expression is 9d + 9, -3d + 1, -d - 1, -d +3.
