Question

the sum of the zeros of x square - 2 x
is

Answer 1

❤x^2-2x
-1*2=-2
1*1=1

x^2-2x
x^2(-1) 2(-1)-2x
(x-1) (x+2)
x-1=0. x+2=0
x=1. x=-2

Answer 2

Here,

The equation is

${x}^{2} - 2x = 0 \: = = = = = > 1$

Let, the zeroes are

$\alpha \: \: and \: \: \beta$

From the equation

${x}^{2} - sx + p = 0 \: = = = = = > 2$

Here,

$\alpha + \beta = s \\ \\ and \: \alpha \beta = p$

Comparing equation 1 and 2

$\alpha + \beta = 2$

So, the sum of zeroes are 2
