Question

if αand β are the zeros of the polynomial x^2+x-2 find thevalue of 1/α -1/β​

Answer 1

Answer:

9

$(\beta - \alpha ) \div \alpha \beta$

$(\beta + \alpha )$

finding...

sum of the roots=-b/a=-1/1=-1

product of the roots=c/a=-2/1

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

=(-1)^2-4(-2)

Step-by-step explanation:

=1+8

=9
