Factor 2x^2+9x-35

$2 x^{2} + 9 x - 35$

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 $a \cdot c = 2 \cdot - 35 = - 70$ and whose sum is $b = 9$ .

Factor $9$ out of $9 x$ .

$2 x^{2} + 9 (x) - 35$

Rewrite $9$ as $- 5$ plus $14$

$2 x^{2} + (- 5 + 14) x - 35$

Apply the distributive property.

$2 x^{2} - 5 x + 14 x - 35$

Step 2

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(2 x^{2} - 5 x) + 14 x - 35$

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

$x (2 x - 5) + 7 (2 x - 5)$

Step 3

Factor the polynomial by factoring out the greatest common factor, $2 x - 5$ .

$(2 x - 5) (x + 7)$

Factor 2x^2+9x-35
