Answer:
C −2a^3+9a^2+45a+6ab^2+18b^2
Step-by-step explanation:
(a+3) ( −2a^2+15a+6b^2)
Distribute the a to the large term in parentheses and the 3 to the large term in parentheses
a ( −2a^2+15a+6b^2)+3 ( −2a^2+15a+6b^2)
−2a^3+15a^2+6ab^2 −6a^2+45a+18b^2
Combine like terms
−2a^3+15a^2−6a^2+6ab^2 +45a+18b^2
-2 a^3 + 9 a^2 + 6 a b^2 + 45 a + 18 b^2
They are both the same. There are 60 seconds in one minute, so 60*3 is 180. Since 180=180, they are equal.

<em><u>Option A</u></em>
<em><u>The solution is:</u></em>
<em><u>Solution:</u></em>
We have to solve the equation f(x) = 0
Let f(x) = 0
Solve the above equation
Take square root on both sides
Thus the solution is found
Answer:
your answer is 0 because it's a horizontal line
