Factor 4x^2+33x+35

$4 x^{2} + 33 x + 35$

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 $a \cdot c = 4 \cdot 35 = 140$ and whose sum is $b = 33$ .

Factor $33$ out of $33 x$ .

$4 x^{2} + 33 (x) + 35$

Rewrite $33$ as $5$ plus $28$

$4 x^{2} + (5 + 28) x + 35$

Apply the distributive property.

$4 x^{2} + 5 x + 28 x + 35$

Step 2

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(4 x^{2} + 5 x) + 28 x + 35$

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

$x (4 x + 5) + 7 (4 x + 5)$

Step 3

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

$(4 x + 5) (x + 7)$

Factor 4x^2+33x+35
