Answer 2

hey !!

GIVEN POLYNOMIAL

ax²-bx+a+4=0. ...(1)

If +4 and -4 zeros of given polynomial. ..

so these value are exits this polynomial.....

first

put x=4 in (1) we get

a×4²-b×4 +a+4=0

=>16a-4b+4=0

=>4a-b=-1. ...(2)

second

put x=-4 in (1) we get

a×(-4)²-b(-4)+a+4=0

=>16a+ 4b=-4

=>4a+b=-1. ...(3)

equation (2)- (3)

we get ...

-2b=0

=>b=0

now put b=0 in (2)

we get,

4a-0= -1

a= -1/4

Thus :-

value of a=-1/4 and b= 0
