Question

verify wheather (_2) and 2 are the zeroes of polynomial 2x² + 2x _ 12​

Answer 1

Answer:

p(-2)=2(-2)^2+2(-2)-12

= 8-4-12

= 8-16=-8

p(2)=2(2)^2+2(2)-12

=8+4-12

=. 8+ ( -8)=8-8=0

=. 0

Sum of zeroes =-b/a

8+0. =-(2)/2

8. =-1

Product of zeroes =c/a

8×0. =-12/2

0. =-6

thus,the relationship between the zeroes and the coefficient of the polynomial 2x^2+2x-12is not verified
