i forget how to like factor these kinda of problems, and some help would be appreciated
4x(sqaured) -4x +1
3+6b+3b(squared)
400-36v(squared)
100x(squared)+180x+81
10n(squared)+100n+250
thankyouu (:

I don't know how that related with trig but here the answers
1) 4x^2-4x+1 <==multiply the constant from the x^ with your last number which is 4. then find to number that gives a 4 when you multiple them and a negative 4 when you add them
4x^2 -2x -2x +1 ==> take common factors out
2x(2x-1) -1(2x-1) ===> always watch out for the signs. you don't want a - for x
(2x-1)(2x-1) <==your answer can be written also as ==>(2x-1)^2
2) 3(b+1)^2 <== make sure your polynomial is in the order of x^2+x+c before you start doing anything
3) -(6v-20)^2<== for this one place the x^2 first and then take out the - sign, remember to change the other one too
4) I can't figure it that one out :(
5) 10(n+5)^2 <== for this one take out the common factor from all of them, its the 10. work from there
Answers with some tips, hope this was helpful
