Answer:
Step-by-step explanation:
Whe have the function
To solve this equation we must factor.
To factor, we need to find the points where the function is equal to zero. So we use the quadratic formula
Where:
a = 3
b = -6
c = 2
Then
finally the correct answer is
Question 1:
<h3>Answer: The number does <u>not</u> change</h3>Removing the zero from 0.76 leads to .76 which is the same as before. Both lead to in scientific notation.
