Answer:
(3)11
Step-by-step explanation:
We are given that

We have to find the sum of positive roots of the equation.




Factor of 336
2,3,4,6,8,7,
Let x=2

x=2 is not the root of equation
x=-2

Hence x=-2 is the root of equation.
x+2 is a factor of equation.
x=3

Therefore, x=3 is the root of equation.






Positive roots are 3 and 8
Sum of positive roots=3+8=11
Option (3) is true.
Answer:
I am going to show you the first steps to complete squares for the given equation: 1) Starting equation: 3x^2 + 9x -4 = 0 2) Add 4 to both sides => 3x^2 + 9x - 4 + 4 = 4 => 3x^2 + 9x = 4 3) Extract common factor 3 in the left side => 3 (x^2 + 3x). Now, compare with a(x^2 + 3x) and you get a = 3. Answer: a = 3.
The answer would be
You got it right
