Kadesha is simplifying the expression below.
Negative (x minus 3) minus 2 (x minus 1)
She lists the steps that she uses to simplify the expression as follows:
Step 1: Distribute β1 through (x minus 3), and distribute β2 through (x minus 1).
Step 2: Rewrite the expression as Negative x minus 3 minus 2 x minus 2.
Step 3: Combine βx and β2x, and combine β3 and β2.
Step 4: The simplified expression is Negative 3 x minus 5.
In which step did Kadesha make the first error?
She made the first error in Step 1 because only β2 should be distributed through the parentheses.
She made the first error in Step 2 because Step 2 should be Negative x + 3 minus 2 x + 2.
She made the first error in Step 3 because βx and β2x cannot be combined.
She made the first error in Step 4 because the simplified expression is Negative x minus 5.
