Question

10 points + brainliest = 15 points!

Answer 1

Answer:

(2x²+1)(4x+3)

Step-by-step explanation:

• 8x³ + 6x² + 4x +3=        regroup as follows
• (8x³ + 4x) + (6x²+3) =
• 4x(2x²+1) + 3(2x²+1)=
• (2x²+1)(4x+3)

Correct choice is the second one

Answer 2

Answer:

(2x^2+1)(4x+3)

Step-by-step explanation:

8x^3 + 6x^2 + 4x+3

Split into two groups

8x^3 + 6x^2       + 4x+3

Factor out 2x^2 from the first group and 1 from the second group

2x^2( 4x+3)  +1( 4x+3)

Factor out (4x+3) from each group

(4x+3) (2x^2+1)

Rearranging the order

(2x^2+1)(4x+3)
