Factor 6x^2-23x+20

$6 x^{2} - 23 x + 20$

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 $a \cdot c = 6 \cdot 20 = 120$ and whose sum is $b = - 23$ .

Factor $- 23$ out of $- 23 x$ .

$6 x^{2} - 23 (x) + 20$

Rewrite $- 23$ as $- 8$ plus $- 15$

$6 x^{2} + (- 8 - 15) x + 20$

Apply the distributive property.

$6 x^{2} - 8 x - 15 x + 20$

Step 2

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(6 x^{2} - 8 x) - 15 x + 20$

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

$2 x (3 x - 4) - 5 (3 x - 4)$

Step 3

Factor the polynomial by factoring out the greatest common factor, $3 x - 4$ .

$(3 x - 4) (2 x - 5)$

Factor 6x^2-23x+20
