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.

Solve step by step.<br> 7x+4(4x-14)=59

ziro4ka [17]

Answer:

$x = 5$

Step-by-step explanation:

$7x+16x-56=59$

$23x -56 = 5 9$

$2 3 x - 5 6 + 5 6 = 5 9 + 5 6$

$23x=115$

$\frac{23x}{23} = \frac{115}{23}$

$x = 5$
