please help, (3x-4)^2+(4x+1)^2=(5x+2)^2
Expand each of the terms out so it looks like this: (3x-4)(3x-4)+(4x+1)(4x+1) = (5x+2)(5x+2) Then: (9x^2-24x+16)+(16x^2+8x+1)= 25x^2+20x+4
to hhsten, i did that and combined the terms. Yet, there not equal does that matter?
you can stil continue to solve: 25x^2-16x+17=25X^2+20x+4 this gives you: 36x=13 x=13/36
thats not a great answer to get, so maybe there is an error, but that is the process
