Expand the binomial first, then distribute the 4:
4 (<em>x</em> + 1)² = 4 (<em>x</em> ² + 2<em>x</em> + 1)
… = 4•<em>x</em> ² + 4•2<em>x</em> + 4•1
… = 4<em>x</em> ² + 8<em>x</em> + 4

Answer:
<h3> 78%</h3>
Step-by-step explanation:
Given
Number of scientist that line in Antarctica during the winter = 1,100
Amount of scientist in the summer = 5,000
Increment = 5000 - 1100
Increment = 3900
percentage change = Increment/Original amount * 100
Percentage change = 3900/5000 * 100
Percentage change = 3900/50
Percentage change = 78%
<em>Hence the percent change in the number of scientists living in Antarctica is 78%</em>
