If Jenny uses factoring to find the zeros of the quadratic function f(x)=2x2−x−1
, which of the following is the factored form of the function?(1 point)
Responses

f(x)=(2x−1)(x+1)

f of x is equal to open paren 2 x minus 1 close paren times open paren x plus 1 close paren

f(x)=(x+2)(x−1)

f of x is equal to open paren x plus 2 close paren times open paren x minus 1 close paren

f(x)=(2x+1)(x−1)

f of x is equal to open paren 2 x plus 1 close paren times open paren x minus 1 close paren

f(x)=(2x+1)(x+1)

f(x) = (2x + 1)(x − 1)

Check: (2x+1)(x−1) = 2x^2 −2x + x −1 = 2x^2 − x −1.
