Answer:
<h3>
-2a³ + 9a² + 6ab² + 45a + 18b² </h3>
Step-by-step explanation:
(a + 3)×(−2a² + 15a + 6b²) =
= a×(−2a² + 15a + 6b²) + 3×(−2a² + 15a + 6b²) =
= -2a³ + <u>15a²</u> + 6ab² - <u>6a²</u> + 45a + 18b² =
= -2a³ + 9a² + 6ab² + 45a + 18b²
2x2x2x2x2 is 2^5 in standard notation
Answer:
b
Step-by-step explanation:
(x+12)^2=1
or

x=1-12 =-11
when
x+12=-1
x=-1-12 =-13
then
x=-11 and x= -13
