Question

If A+B are the zero of the polynomial ax.^2+bx+c then A+B=

Answer 1

Answer:

If A,B are the zeros of the polynomial

then

Sum of the zeros = -b/a

so,A+B= -b/a

Answer 2

Answer:

-b/a

Step-by-step explanation:

In Quadratic equations

it is proved

(let A be α and B be β)

In ax²+bx+c,α and β are roots thus

α+β = -b/a

αβ = c/a

Putting values

A+B = - b/a
