Question

find (x+4) exponent of 2

Answer 1

x^2+8x+16

Answer 2

\[(x+4)^{2}\]

Answer 3

\[(x+4)^2=(x+4)(x+4)\] is a start
then do the usual four multiplications

Answer 4

how? can you explain step by step? please

Answer 5

you can either use the FOIL method or you can multiply everything in the first parenthesis by everything in the second parenthesis.....so how do you want to proceed

Answer 6

but how does the foil method apply to that?

Answer 7

first of all, do you see how we got (x + 4)(x + 4) from (x + 4)^2 ?

Answer 8

oh okay i see now i was just going to ask. and then foil that, right?

Answer 9

right...do you know how ?

Answer 10

let me try it on paper

Answer 11

sure thing..

Answer 12

\[x{2} +8+4x\]

Answer 13

here the formula is
a^2+2ab+b^2
here a=x, b=4

Answer 14

no...

(x + 4)(x + 4)

F -- multiply first terms in each set....x * x = x^2
O -- multiply outside terms in each set....x * 4 = 4x
I -- multiply inside terms in each set...4 * x = 4x
L -- multiply last terms in each set...4 * 4 = 16
so now we have..
x^2 + 4x + 4x + 16 -- combine like terms
x^2 + 8x + 16

any questions ?

Answer 15

\[x{2} + 16+4x + 16 ???\]

Answer 16

ahhh i see what i did wrong.

Answer 17

nope no questions... for now. thanks for your help

Answer 18

anytime :)
