Hi!
x^2+40x-1600
(x)^2+ 2(x)(10)-(40)^2
[We got the expanded form of identity- (a-b)^2]
Trinomial can not be factored. The answer is -
x^2+40x-1600
Hope it helps...!!!

rathieshaan164p0ab7g:
it will be x^(2)+80x-1600
oops! wait
ah reported?

it is identity of (a-b)^2
So the value of x is
(x-40)= 0
x= 40
So the value of x is
(x-40)= 0
x= 40
no it will result in x^(2)+80x-1600
so i think some sign mistake is there
no the question is like that
I'm trying but value of x is in points
trinomial cant be factored
this is the answer
