Question

Find the two products below. Compare and contrast, in complete sentences, the similarities and differences of the two.

(x + 4)(x − 4) and (x + 4)(x + 4)

Answer 1

x^2-16 the first is binomial

the second will be some trinomial

Answer 2

\[(x-4)(x+4) = (x^{2}-16)\]
Difference of squares! ->Binomial
\[(x+4)(x+4) = (x+4)^{2}\]
The whole square formula ->Trinomial

Answer 3

x^2+8*x+16

x^2 -16

for the first one the last term the one without variable is same as second excep with a - sign. The middle term is non existant =0, and the first term the x^2 is same on both.

Answer 4

I'm confused @timo86m

Answer 5

x^2+8*x+16 = (x + 4)(x + 4)

x^2 -16 = (x + 4)(x - 4)
^ same
^ in bottom one middle term is 0 on top it will be 8*x
^ last term in bottom one the number is same only the sign is -

Answer 6

ohhh okahy! i understand what you're saying <3 thanks :)
