cestrela7 [59]

Answer:

(a) -\sqrt{10}y

(b) -\sqrt{3}y

Step-by-step explanation:

(a) \sqrt{10y^{2}} can also be written as \sqrt{10} x \sqrt{y^{2}}

the \sqrt{y^{2}} = ± y

Therefore :

\sqrt{10y^{2}} = ±\sqrt{10}y

since it was given that y < 0 , then the factor will be -\sqrt{10}y

(b) \sqrt{3y^{2}} can also be written as : \sqrt{3} x \sqrt{y^{2}}

Therefore , one of the factor is -\sqrt{3}y
