Question

(x+3) (x-3)+(3+x)(3-x)

Answer 1

Resposta:

(x+3) (x-3)+(3+x)(3-x)

=0

Let's solve this account with value of x = 1. Because the result will be the same only the calculation will be changed.

(x+3)(x−3)+(3+x)(3−x)

Evaluate for x=1

(1+3)(1−3)+(3+1)(3−1)

=4(1−3)+(3+1)(3−1)

=(4)(−2)+(3+1)(3−1)

=−8+(3+1)(3−1)

=−8+4(3−1)

=−8+(4)(2)

=−8+8

=0
