Rachel is using grouping to find the factors of a quadratic expression. She has reached the step shown below. Determine the factored form and the standard form of the quadratic polynomial.

Factored form: (3x + 4)(x - 2)
Standard form: 3x2 - 2x + 8

Factored form: (3x - 4)(x + 2)
Standard form: 3x2 + 2x - 8

Factored form: (3x + 2)(x + 4)
Standard form: 3x2 + 2x + 8

Factored form: (3x - 2)(x - 4)
Standard form: 3x2 - 2x - 8
