10x3 + 2x2 + 5x+1
A. (2x2 + 1)(x + 1)
O B. (2x2+ 1)(5x + 1)
OC (5x2 + 1)(x+1)
OD. (5x2+ 2)(5x+1)

B

Step-by-step explanation:

Given

10x³ + 2x² + 5x + 1 ( factor the first/second and third/fourth terms )

= 2x²(5x + 1) + 1(5x + 1) ← factor out (5x + 1) from each term

= (5x + 1)(2x² + 1) → B

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
