Factor 8x^2+10x+3

$8 x^{2} + 10 x + 3$

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 $a \cdot c = 8 \cdot 3 = 24$ and whose sum is $b = 10$ .

Factor $10$ out of $10 x$ .

$8 x^{2} + 10 (x) + 3$

Rewrite $10$ as $4$ plus $6$

$8 x^{2} + (4 + 6) x + 3$

Apply the distributive property.

$8 x^{2} + 4 x + 6 x + 3$

Step 2

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(8 x^{2} + 4 x) + 6 x + 3$

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

$4 x (2 x + 1) + 3 (2 x + 1)$

Step 3

Factor the polynomial by factoring out the greatest common factor, $2 x + 1$ .

$(2 x + 1) (4 x + 3)$

Factor 8x^2+10x+3
