Answer:
3 + x[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Note that [tex]\sqrt{a}[/tex] × [tex]\sqrt{a}[/tex] = a
Given
[tex]\sqrt{3}[/tex] ([tex]\sqrt{3}[/tex] + x ) ← distribute parenthesis by [tex]\sqrt{3}[/tex]
= [tex]\sqrt{3}[/tex] × [tex]\sqrt{3}[/tex] + [tex]\sqrt{3}[/tex] × x
= 3 + x[tex]\sqrt{3}[/tex]
