Answer:

Step-by-step explanation:
cannot be factorised in the form (x+b)(x-b) unless one of the b's is zero, so I wonder if the expression is incomplete?
To factorise
, take out the common factor
:

Therefore, x = 0 and x = 4
- - - - - - - - -
factorised in the form (x+b)(x-b) would be 
but it is not usual to have a zero in a factorised form.
Answer: oooo i know this one its 4 hopefully i helped

Answer:
Step-by-step explanation:
value of 4, and you want to square it or exponent 2
so 4^2 = 4x4
=16
What is ^-2
It does the same operation however because to is negative it really means putting 4 in the denominator so 2 becomes positive. Inverse of the exponent 2
1/4^2 is the same as 4^-2
which will both give 1/16
Answer: - 3/8
