Answer:

By multiplying the term by itself (x+1)(x+1)

Some people like to use the box technique, which formats like this:

x + 1

x x^2 1x

1 1x 1

The terms multiply in columns, and then add all together

x^2 + 1x + 1x + 1 can be simplified to x^2+2x+1 = 0, which is the perfect square of (x+1)^2 = 0

Answer:

0.3 or 30%

Step-by-step explanation:

The professors will only seek a smaller publisher if they cannot place the statistics book with a major publisher. If the probability of getting a major publisher is 40% and the probability of getting a smaller publisher is 50%, then the probability that the statistics book would wind up being placed with a smaller publisher is given by:

$P=(1-P(major))*P(minor)\\P=(1-0.4)*0.5\\P=0.3$

The probability is 0.3 or 30%.
