Question

x^2-10x+25-b^2

Answer 1

what???

Answer 2

\[x ^{2}-10x+25-b ^{2} \] i need to factor it and i forgot how, it ends with 3 term multiplied by 3 terms but i don't remember how.

Answer 3

Rewrite it as (x-5)^2 - b^2. That's the difference of two squares. Rewrite it like that :-)

Answer 4

You should end up with (x- 5 - b)(x - 5 + b)

Answer 5

x=(10(+or-)sqrt(100-100+4b^2))/2
x=(10(+or-)2b)/2
x=5+b
and x =5-b

Answer 6

which means @bmp is also correct
