Find the Product 10a(a-10b)

$10 a (a - 10 b)$

Apply the distributive property.

$10 a \cdot a + 10 a (- 10 b)$

Multiply $a$ by $a$ by adding the exponents.

Move $a$ .

$10 (a \cdot a) + 10 a (- 10 b)$

Multiply $a$ by $a$ .

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

Rewrite using the commutative property of multiplication.

$10 a^{2} + 10 \cdot - 10 a b$

Multiply $10$ by $- 10$ .

$10 a^{2} - 100 a b$
