Factor 6x^2+5x-1

$6 x^{2} + 5 x - 1$

Step 1

For a polynomial of the form $a x^{2} + b x + c$ , rewrite the middle term as a sum of two terms whose product is $a \cdot c = 6 \cdot - 1 = - 6$ and whose sum is $b = 5$ .

Factor $5$ out of $5 x$ .

$6 x^{2} + 5 (x) - 1$

Rewrite $5$ as $- 1$ plus $6$

$6 x^{2} + (- 1 + 6) x - 1$

Apply the distributive property.

$6 x^{2} - 1 x + 6 x - 1$

Step 2

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(6 x^{2} - 1 x) + 6 x - 1$

Factor out the greatest common factor (GCF) from each group.

$x (6 x - 1) + 1 (6 x - 1)$

Step 3

Factor the polynomial by factoring out the greatest common factor, $6 x - 1$ .

$(6 x - 1) (x + 1)$

Factor 6x^2+5x-1
