Factor 15x^2-13x+2

$15 x^{2} - 13 x + 2$

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 $a \cdot c = 15 \cdot 2 = 30$ and whose sum is $b = - 13$ .

Factor $- 13$ out of $- 13 x$ .

$15 x^{2} - 13 (x) + 2$

Rewrite $- 13$ as $- 3$ plus $- 10$

$15 x^{2} + (- 3 - 10) x + 2$

Apply the distributive property.

$15 x^{2} - 3 x - 10 x + 2$

Step 2

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(15 x^{2} - 3 x) - 10 x + 2$

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

$3 x (5 x - 1) - 2 (5 x - 1)$

Step 3

Factor the polynomial by factoring out the greatest common factor, $5 x - 1$ .

$(5 x - 1) (3 x - 2)$

Factor 15x^2-13x+2
