Put it into two binomilals that multipy together to create the polynomial. For example: 5K(squared)-2k-7 is factored out as: (5k+1)(-7K+1)
The K stands for thousand. So 5k is 5,000 and 7 3K is either 73,000 or 7,000 and 3,000.

Subtract is to take away a certain portion of a number. For example, if you subtract 5 from 7 (7-5), you take off 5 parts of 7, and get 2 as your answer.
-7
(k + 1)(5k - 7)
Put it into two binomilals that multipy together to create the polynomial. For example: 5K(squared)-2k-7 is factored out as: (5k+1)(-7K+1)
35 + 2k = 9k subtract 2k from each side 35 + 2k - 2k = 9k - 2k 35 = 7k divide both sides integers by 7 35/7 = (7/7)k 5 = k check in original equation 35 + 2(5) = 9(5) 35 + 10 = 45 45 = 45 checks out
8k +2k + 7 = 10k + 7
5k + 7 + 3k can be simplified into 8k + 7
It is: 5k-7
The K stands for thousand. So 5k is 5,000 and 7 3K is either 73,000 or 7,000 and 3,000.
8k-7-3k=1? 5k-7=1 5k=8 k=8/5 8k-7 =-3k+1 11k-7=1 11k=8 k=8/11 8k-7-3k+1=0 5k-6=0 5k=6 k=6/5=1.2 depends on where = sign is in the question
2k + 17 = 32k = -14k = -7
It is 8k+7 simplified
2k - 7
k=-7
