The sum of the roots of 3x 2 + 11x - 4 = 0 is<br><br> -11/3<br> -4/3<br> 11/3<br> 4/3
givi [52]

Answer:

The correct option is 1.

Step-by-step explanation:

If a quadratic equation is defined as

ax^2+bx+c=0             .... (1)

Then the sum of the roots is -b/a and the product of roots is c/a.

The given equation is

3x^2+11x-4=0          ... (2)

From (1) and (2) we get a=3, b=11 and c=-4.

The sum of roots is

\frac{-b}{a}=-\frac{11}{3}

The sum of roots is -\frac{11}{3}.

Therefore the correct option is 1.

In-s [12.5K]

Answer:

Step-by-step explanation:

let ????=g

g(x)=x|x|

if x<0,then |x|=-x

-67<0

|-67|=-(-67)=67

g(-67)=-67(67)=-67²

f(-67)=(-67)²=67²

f(-67)+g(-67)=67²-67²=0
