i have (4x+1)squared
and the answer 16xsquared +1 if i use x=2 then do the answers for these match
6p-4/2 +8
6p-2+8
6p+6
does the answers match if i use x=2
You're asking if:
(4x + 1)^2 = 16x^2 + 1, when x = 2
(4(2) + 1)^2 = 16(2)^2 + 1
(9)^2 = 64 + 1
81 = 65; no.
I'm confused what you're trying to ask for hte second part. You're asking if the "answers match" if you use x = 2, but you have p as your variable.
Further, you have an expression.
Perhaps you could clarify what you're asking for.
