Factor a^2-10ab+24b^2

$a^{2} - 10 a b + 24 b^{2}$

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 $a \cdot c = 1 \cdot 24 = 24$ and whose sum is $b = - 10$ .

Reorder terms.

$a^{2} + 24 b^{2} - 10 a b$

Reorder $24 b^{2}$ and $- 10 a b$ .

$a^{2} - 10 a b + 24 b^{2}$

Factor $- 10$ out of $- 10 a b$ .

$a^{2} - 10 (a b) + 24 b^{2}$

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

$a^{2} + (- 4 - 6) (a b) + 24 b^{2}$

Apply the distributive property.

$a^{2} - 4 (a b) - 6 (a b) + 24 b^{2}$

Remove unnecessary parentheses.

$a^{2} - 4 a b - 6 (a b) + 24 b^{2}$

Remove unnecessary parentheses.

$a^{2} - 4 a b - 6 a b + 24 b^{2}$

Step 2

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(a^{2} - 4 a b) - 6 a b + 24 b^{2}$

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

$a (a - 4 b) - 6 b (a - 4 b)$

Step 3

Factor the polynomial by factoring out the greatest common factor, $a - 4 b$ .

$(a - 4 b) (a - 6 b)$

Factor a^2-10ab+24b^2
