The brackets are first, then the multiplication
Answer:
The first answer, 3 times the square root of x squared is correct.
Answer:
<em>12 </em>
<em> + 28 </em>
<em> - 60 r³ + 28 r² </em>
Step-by-step explanation:
a(b ± c) = ab ± ac (distributive property)

2r²(6r³ + 14r² - 30r + 14) = <em>12 </em>
<em> + 28 </em>
<em> - 60 r³ + 28 r²</em>
I'm pretty sure it's the second and third one!
