Question

Solve (x+16)^2 + 18(x+18) = (x + 16)(x+18)

Answer 1

Expand everything out, combine like terms. Get the x terms on one side and the constants on the other. Solve for x.

Answer 2

Imma type the first part then I will continue solving.

x^2+256+18x+324=x^2+18x+16x+288

Answer 3

here is the next part

x^2+18x+580=x^2+34x+288

Answer 4

next

x^2+18x+292=x^2+34x

Answer 5

then

x^2-16x+292=x^2

Answer 6

(x+16)^2 + 18*(x+18)-(x + 16)*(x+18)=0

expanding-->

16*x+292 = 0

x = -73/4

Answer 7

yeah that's the other way of doing it. I guess I was taught different lol

Answer 8

the rest of mine was

-16x+292=0
-16x=292
x= -18.25 or -73/4

Answer 9

You are right pandaluver44, I just wanted to share my solution...
