Fill in the blanks to make a quadratic whose roots are $1$ and $-1.$   
x^2 + ___ x + ___    

 

x = + 1     ==>>   therefore the factor is (x – 1)    

x = – 1     ==>>   therefore the factor is (x + 1)    

 

(x + 1)(x – 1)  =  x2 – 1    

 

so, fill in the blanks with 0 and – 1 respectively, thus:     x20x  + ( 1)
