What are the solutions to f(x)=x^2-1?

1 and -1

Step-by-step explanation:

Factoringfind a number set that equals zero and when multiplyed, becomes -1.

1 and -1 multiply to -1 and equal 0,

so x^2-1 turns into (x+1)(x-1)

solve for both x+1=0 and x-1=0

x+1=0

x=-1

x-1=0

x=1

it would be:

c.parallelogram.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
