Question

find a quadratic polynomial whose zeores are -9 and 1/9​

Answer 1

Answer:

Quadratic polynomial=9x²+80x-9

Step-by-step explanation:

α=(-9), β=1/9

Quadratic polynomial

=x²-(α+β)x+αβ

=x²-(-9+1/9)x+(-9)(1/9)

=x²-((-81+1)/9)x+(-1)

=x²-(-80)x/9-1

=x²+80x/9-1

Multiple each term by 9

=x²×9+80x/9×9-1×9

=9x²+80x-9
