I believe B. is your answer. If you use the ac method, you will multiply 8 and 3 which is 24. So now, what factors of 24 will give you 10?6 and 4
Now substitute
[tex]8 {x}^{2} + 4x + 6x + 3[/tex]
Now do factorization by grouping.
[tex]4x(2x + 1) + 3(2x + 1)[/tex]
Therefore, your answer is (4x+3)2x+1)
