Question

find the polynomial whose zeros are minus 1 and 8​

Answer 1

Answer:

SINCE TWO ZEROES ARE -1 N 8

ALPHA =1

BITA= 8

NOW ,WE KNOW (ALPHA + BITA) = -b/a

= +9

ALSO WE KNOW (ALPHA)(BITA) = c/a

=7

Thus, polynomial should be in the form: ax² +bx+c=0

thus the polynomial you require is: 1x ²- 9x+ 7=0
