false
Step-by-step explanation:
-5,-4,-3,-2,-1,0,1,2,3,4,5
 
        
                    
             
        
        
        

If x²-1 is a factor of the polynomial, both x-1 and x+1 are factors of it.
According to the remainder theorem, if a binomial x-a is a factor of a polynomial p(x), then p(a)=0.
If x-1 and x+1 are factors of the polynomial p(x)=ax⁴+bx³+cx²+dx+e, then p(1)=0 and p(-1)=0.
 
        
             
        
        
        
 <span>[H+] x [(CIO2)-]/[HCIO2]</span>
        
             
        
        
        
Step-by-step explanation:
Given 
x² - 9x + 20 = 0 
x² - ( 4 + 5) x + 20 = 0 
x² - 4x - 5x + 20 = 0 
x ( x - 4 ) - 5 (x - 4 ) = 0 
(x - 4 ) ( x - 5 ) = 0 
Either 
x - 4 =0 
x = 4 
or 
x - 5 =0 
x = 5 
x = 4 and 5
