Question

Find the zero
of polynomial p(x)=x^2+4x+2​

Answer 1

Answer:

-2,-2

Step-by-step explanation:

x²+4x+2

splitting the middle term we get

x²+x(2+2)+2

=x²+2x+2x+2=0

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

grouping the factors we get

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

x+2=0 x=-2

x+2=0 x=-2

x=-2,-2

hence zeroes of the polynomial x²+4x+2 are -2, -2
