Answer 1

Answer:

hey mate ❤️....here is your answer...

given,one zero of the polynomial x^2+a is (-3)

According to the question

x^2+a=0

=>(-3)^2+a=0

=>9+a=0

=>a=(-9)

so, putting the value of a in the equation

we get,

x^2+(-9)=0

=>x^2=9

=>x^=3^

=>x=3

the other zero of the polynomial x^+ a is 3
