${yr}^{2} = l m (\frac{x}{m} - s a)$

Step 1

Apply the distributive property.

${yr}^{2} = l m \frac{x}{m} + l m (- s a)$

Step 2

Cancel the common factor of $m$ .

Step 2.1

Factor $m$ out of $l m$ .

${yr}^{2} = m l \frac{x}{m} + l m (- s a)$

Step 2.2

Cancel the common factor.

${yr}^{2} = m l \frac{x}{m} + l m (- s a)$

Step 2.3

Rewrite the expression.

${yr}^{2} = l x + l m (- s a)$

Step 3

Rewrite using the commutative property of multiplication.

${yr}^{2} = l x - l m s a$
