Question

find alpha and beta are zeros of polynomial x square - 2 x minus 3 then Alpha minus beta is​

Answer 1

Answer:

sorry

Step-by-step explanation:

I don't know the answer

Answer 2

Given:-

${x}^{2} - 2x - 3$

on factorizing we get

${x}^{2} - 3x + x - 3 \\ so \: we \: get \\ x(x - 3) + 1(x - 3)$

$so \: the \: next \: step \: is \:$

(x+1) (x-3)

x+1 =0, x-3 =0

So x= -1 and x= 3

so -1 and 3 are zeros of polynomial

lets take

$\alpha = - 1 \: and \: \beta \: = 3$

so,

$\alpha - \beta = - 1 - ( + 3) \\ = - 1 - 3 \\ = - 4$

Hope you understand thank you
