Question

find the zeroes of a polynomial p(x)=2x2-9x+10​

Answer 1

$\huge{\orange{\underline{\red{\mathtt{ANSWER}}}}}$

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

Answer 2

Answer:

the know that the sum of zeroes=-b/a

1. @+b=-b/a
2. than
3. @+b=9/2
4. i.e a=2,b=9,c=1
5. then the sum of zeroes of the polynomial is 9/2
