Answer 1

Answer: 3

Explanation:

Answer 2

Taking out the parentheses of expression
(5x2 + 3x + 4) − (2x2 + 5x − 1)

= 5x2 + 3x+ 4 -2x2 - 5x + 1

Grouping together the like terms and arranging the expression:
= 5x2 - 2x2 + 3x - 5x + 4 + 1

Combining the like terms:
= 3x2 - 2x + 5

Therefore,
A = 3
