You have the correct solution, are you sure this is the exact wording/equation?
hi,
i need to find the values of A and B to this question:
given that x^2 +12x +A ≡ (x+B)^2
Find values of A and B.
im unsure what to do because before i did:
(x+6) (x+6)
= x^2+12+36
A=36 B=6
however it was wrong so i need to know where i am going wrong and how i get it correct!
help would be great!
thanks!
She isn't saying that you're wrong. She is saying that your method is concerning because it looks like you've randomly guessed.
Start the problem from scratch and try to solve it this way: expand the brackets on the right hand side, and then equate the coefficients.
