Answer:
option A . 6x^2 + 11x + 3 is the correct answer.
Step-by-step explanation:
Identity
(a + b)(c + d) = ac + ad + bc + bd
To find (2x + 3)(3x + 1)
Here a = 2x, b = 3 , c = 3x and d = 1
(2x + 3)(3x + 1) = 2x(3x + 1) + 3(3x+ 1)
= 2x*3x + 2x + 3*3x + 3
= 6x^2 + 2x + 9x + 3
= 6x^2 + 11x + 3
We get a quadratic equation in terms of variable x
Therefore option A . 6x^2 + 11x + 3 is the correct answer.
