Answer 2

"x2" was replaced by "x^2"

1) Equation at the end of step 1.

(3x² - 2x) - 1

2) Trying to factor by splitting the middle term.

2.1 Factoring 3x²-2x-1

The first term is, 3x² it's coefficient is 3.

The middle term is, -2x it's coefficient is -2.

The last term, "the constant", is -1.

Step 1 - Multiply the coefficient of the first term by the constant 3 · -1 = -3

Step 2 - Find two factors of -3 whose sum equals the coefficient of the middle term, which is -2.

Step 3 - Rewrite the polynomial splitting the middle term using the two factors you used in step 2.

Step 4 - Add up the first 2 terms, pulling out like factors and then add up the last 2 terms, pulling out common factors.

Step 5 - Add up the four terms of step 4. (Which is the desired factorization).

Final result - (x - 1) · (3x + 1).
