Factor 10y^2+17y+3

$10 y^{2} + 17 y + 3$

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 $a \cdot c = 10 \cdot 3 = 30$ and whose sum is $b = 17$ .

Factor $17$ out of $17 y$ .

$10 y^{2} + 17 (y) + 3$

Rewrite $17$ as $2$ plus $15$

$10 y^{2} + (2 + 15) y + 3$

Apply the distributive property.

$10 y^{2} + 2 y + 15 y + 3$

Step 2

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(10 y^{2} + 2 y) + 15 y + 3$

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

$2 y (5 y + 1) + 3 (5 y + 1)$

Step 3

Factor the polynomial by factoring out the greatest common factor, $5 y + 1$ .

$(5 y + 1) (2 y + 3)$

Factor 10y^2+17y+3
