Question

1.
Find the sum of the zeroes of a polynomial P(x) = 2x - 9x + 10​

Answer 1

Step-by-step explanation:

we already know that

sum of zeroes = -b/a

on comparing the equation with general formulas of pair of linear equation , we get

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

then ,

$\alpha + \beta = \frac{9}{2}$

because , a=2. ,. b=-9 , c= 1

so the sum of zeroes of polynomial is 9/2
