What are the zeros of y = x^2 + 9x +14?

Step-by-step explanation:

obtain zeros P(x)=x  2

+9x+14

→ for zeros find P(x) = 0

x  

2

+9x+14=0

x  

2

+7x+2x+14=0

x(x+7)+2(x+7)=0

(x+7)(x+2)=0

x=−7 or x=−2

zeros is -7 & -2

→P(−7)=(−7)  

2

+9(−7)+14

=+49−63+14

=0

→P(−2)=(−2)  

2

+9(−2)+14

=4−18+14

=0

x= -7,x= -2

The zerores of polynomial y are -2 & -7
