Question

Using factorisation find the values of x in the following equations that will satisfy
these equations.
1
1 - x2 = 0​

Answer 1

Answer:

x²=1

root on both sides

x=±√1

x=+1 or-1

by factorization method

(x+1)(x-1) =0

if a*b=0

a=0 or b=0

in the same way

x+1=0 or (x-1) =0

x=-1 or x=+1
