Answer:

$(x + 2)(3x + 5)$

Step-by-step explanation:

$3 {x}^{2} + 11x + 10 \\ 3 {x}^{2} + 6x + 5x + 10 \\ (3 {x}^{2} + 6x) + (5x + 10) \\ \frac{3x}{3x} (3 {x}^{2} + 6x) + \frac{5}{5} (5x + 10) \\ 3x(x + 2) + 5(x + 2) \\ \frac{x + 2}{x + 2} (3x(x + 2) + 5(x + 2)) \\ (x + 2)(3x + 5)$

Answer: Option b

$f (1) = 0$

Step-by-step explanation:

For a function of the form

$f (x) = ax ^ n + bx ^ {n-1} + ... + c$

Where n is the main exponent of the polynomial and a, b c are the coefficients of the variables then this polynomial can be written based on its factors as

$f (x) = a (x-h) (x-k) (x-s)...$
