Answer

7 (a). $ x (x - y)$ 7 (b). $ \sin\theta (\sin\theta- \cos\theta)$

Work Step by Step

7 (a). Given expression is- $x^{2} - xy$ = $ x (x - y)$ ($x$ is the common factor) 7 (b). Given expression is- $\sin^{2} \theta - \sin\theta \cos\theta$ = $ \sin\theta (\sin\theta- \cos\theta)$ ($\sin\theta$ is the common factor)
