Question

Find zero of polynomialp(x) = (x-2)²-(x+2)²

Answer 1

Answer:

0 is the zero of the polynomial p(x)

Answer 2

Answer:

zeros are x= -2

Step-by-step explanation:

factor out                    so....

(x-2)(x-2)                             =2 (x^2+4)

= x^2 -2x-2x+4                    *Notice square of 4 is 2

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

=x^2+ 2x+2x +4

collect like terms

= 2x^2 +8

i hope my solution helps you understand why there is only one root (zero)
