Question

If the product of zeros of the polynomial ax^2-6x-6 is 4, find the value of a. Find the sum of zeros of the polynomial.

Answer 1

hey mate!!

let zeroes be

$\alpha \\ \beta$

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

$\alpha \beta = \frac{c}{a}$

$4 = \frac{ - 6}{a}$

$a = \frac{ - 6}{4}$

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

$\alpha + \beta = \frac{ - ( - 6)}{ \frac{ - 6}{4} } = \frac{ - 1}{4}$

hope the answer helps u
