Question

sum or the roots of the quadratic polynomial 7x2-3x+1 is​

Answer 1

Answer:

Formula..

Let the root of quadratic polynomial is is r and t

r+t = ( b/a)

Here ,

b= -3 , a= 7

(r+t) = ( -3/7)

mark me as brai

Answer 2

Answer:

$\frac{3}{7}$

Step-by-step explanation:

Let the root of a quadratic polynomial is α and β

$7x^{2} -3x+1=Ax^{2} +BX+C\\here A=7,\\B=-3,\\C=1$

The formula of sum of roots of a quadratic  polynomial (α+β) = $\frac{-B}{A}$

putting the value of B and A from above

$=-\frac{-3}{7} \\\\=\frac{3}{7}$
