Factor 5x^2-26x-24

$5 x^{2} - 26 x - 24$

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 $a \cdot c = 5 \cdot - 24 = - 120$ and whose sum is $b = - 26$ .

Factor $- 26$ out of $- 26 x$ .

$5 x^{2} - 26 (x) - 24$

Rewrite $- 26$ as $4$ plus $- 30$

$5 x^{2} + (4 - 30) x - 24$

Apply the distributive property.

$5 x^{2} + 4 x - 30 x - 24$

Step 2

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(5 x^{2} + 4 x) - 30 x - 24$

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

$x (5 x + 4) - 6 (5 x + 4)$

Step 3

Factor the polynomial by factoring out the greatest common factor, $5 x + 4$ .

$(5 x + 4) (x - 6)$

Factor 5x^2-26x-24
