PLEASE HELP WITH MATH QUESTION!! EXPLANATION NEEDED TOO!

Answer 1

Answer:

Matt should have factored out the leading coefficient 2 on the second step before completing the square

Step-by-step explanation:

To complete the square, you must first factor the leading coefficient from the first two terms.

y = 2x² − 10x − 4

y = 2 (x² − 5x) − 4

y = 2 (x² − 5x + 25/4 − 25/4) − 4

y = 2 (x² − 5x + 25/4) − 25/2 − 4

y = 2 (x − 5/2)² − 33/4
