Question 5 (2 points) Sasha was asked to simplify the following expression: x2 - 25 X x2 - 5x - 14 x2 + 7x+ 10 x2 - 49 Here is the work she completed to simplify the expression: Step 1. Factor the x2 - 25 x2 - 5x - 14 (x + 5)(x - 5) (x - 7)(x +2) = X expression. x2 +7x + 10 X x2 - 49 (x + 5)(x + 2) (x - 7) (x + 7 ) Step 2. Reduce terms (* * 5) ( x - 5 ) (x - 5) that are identical. X IT ( x + 7 ) (x + 7) Step 3. Determine the (x + 7 + 0 NPVS. x * - 7 Step 4. Give the final (x - 5) answer. ( X + 7) , X 7-7 Did Sasha make any errors? If so, explain the error and state the correct answer to the simplification of the expression
