(b-4) squared
It is: (B -10)(B +10) when factored
To evaluate it you need to know both b and a. But it is possible to factorise it as follows: b2-a2 = (b-a)*(b+a)

hello
Oh, dude, that's just the difference of squares formula! It's like A squared minus B squared equals (A + B)(A - B). So, yeah, you just gotta remember that little math nugget next time you're trying to impress someone at a party or something.
(b-4) squared
B squared equals c squared minus a squared then to find B take the square root of you answer for b squared
(b-c)(a+b)-ac
It is: (B -10)(B +10) when factored
To evaluate it you need to know both b and a. But it is possible to factorise it as follows: b2-a2 = (b-a)*(b+a)
It simplifies to 5a+4 !
(b + 8)(b - 1)
(a - 2b)(2a - b)
If your Problem is organized like this: A x squared plus B x plus C, the equation is: (B plus or minus the square root of(B squared minus 4 A C)) over 2A
