Question

the equation 4x²+c=8x has two distinct roots find the sum of roots​

Answer 1

Step-by-step explanation:

In the equation,

ax²+bx+c = 0

The sum of two roots is =>

$\alpha + \beta = - \frac{b}{a}$

So, in this above equation,

$4{x}^{2} + c \: = 8x \\ 4 {x}^{2} - 8x + c = 0 \\ 4{x}^{2} + ( - 8)x + c = 0$

So, here,

The sum of two roots is =>

$\alpha + \beta = - \frac{( - 8)}{4} \\ = 2$
