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

 

Since the roots are +1 and –1 then the factors are (x – 1) and (x + 1) respectively.    

 

Multiplied out, the result is x2 – 1    

 

Therefore the first blank holds a          0    

and the second blank holds a            –1
