Answer:

The answer is (B) ⇒ 3x² - 11x - 4 = 0

Step-by-step explanation:

∵ 3x² - 11x - 4 = 0

∴ (3x + 1)(x - 4) = 0

∴ 3x + 1 = 0 ⇒ 3x = -1 ⇒ x = -1/3

∴ x - 4 = 0 ⇒ x = 4

∴ The solution set of the polynomial is { -1/3 , 4 }

Answer:

The right choice is B. 3x^2-11x - 4=0  

Step-by-step explanation:

Let's solve your equation step-by-step.

3x²−11x−4=0

Step 1: Factor left side of equation.

(3x+1) (x−4) = 0

Step 2: Set factors equal to 0.

3x + 1=0 or  x− 4=0

x =  −1 /3  or x = 4
