Question

if the product of zeros of ax square - 6 x minus 6 is 4 find the sum of zero ​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

-4

Step-by-step explanation:

p(x) = ax^2 - 6x - 6 = 0

Let -6 = b  &  c

Let the roots be α and β.

$\alpha \beta = 4 \\ \\ \frac{c}{a} = 4 \\ \\ \frac{-6}{a} = 4 \\ \\ a = \frac{-6}{4} \\ \\ a = -\frac{3}{2}$

$\alpha + \beta = \\ \\ - \frac{b}{a} \\ \\ -\frac{-6}{-\frac{3}{2}} \\ \\ \frac{6}{-\frac{3}{2}} \\ \\ \\ 6 \div -\frac{3}{2} \\ \\ 6 \times - \frac{2}{3} \\ \\ \\ \bold{-4}$

∴ Sum is -4.

Thank you. :-)
