I don’t know but hope you find out!
Answer
given,
a) x-1=0
adding both side with 1
x = 1
b) x + 1 =0
subtracting both side by 1
x = -1
c) x²- 1 =0
x² = 1
taking square root
x = √1
x = 1
d) x²+ 1 =0
x² = -1
taking square root
x = √-1
x = i (iota)

Step-by-step explanation:
<span>Solution :-
Given :- Total value of restaurant bill = 90 $
Tip added in the bill = 18%

Therefore The tip value is = 16.2$
Therefore the total amount is
restaurant bill + tip value = 90$ + 16.2$ = 106.2 $
Ans : - option is c ie 106.2 $.</span>
The complete factor of the expression

correct option is D.
<h3>What is a factorization?</h3>
It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The expression is .
To solve the expression properly we have to take common (2x²). Then we have
The factor is .
