Step 1.2.1

Move $90$ to the left of $l$ .

$a = (90 \cdot l + l (- l)) m^{2}$

Step 1.2.2

Rewrite using the commutative property of multiplication.

$a = (90 \cdot l - l \cdot l) m^{2}$

$a = (90 \cdot l - l \cdot l) m^{2}$

$a = (90 \cdot l - l \cdot l) m^{2}$

Step 2

Multiply $l$ by $l$ by adding the exponents.

Step 2.1

Move $l$ .

$a = (90 l - (l \cdot l)) m^{2}$

Step 2.2

Multiply $l$ by $l$ .

$a = (90 l - l^{2}) m^{2}$

$a = (90 l - l^{2}) m^{2}$

Step 3

Simplify by multiplying through.

Step 3.1

Apply the distributive property.

$a = 90 l m^{2} - l^{2} m^{2}$

Step 3.2

Reorder $90 l m^{2}$ and $- l^{2} m^{2}$ .

$a = - l^{2} m^{2} + 90 l m^{2}$

$a = - l^{2} m^{2} + 90 l m^{2}$
