Answer:
Only the 2 is negative. The 2nd step is incorrect.
Step-by-step explanation:
In this equation, she did the 2nd step wrong because when you use the factors of 8, -4 and -2 just get you -6, not -2. So, you would have a -4 and a positive 2.
First, you are going to distribute the 3 into the (6x+2x) and the 8 into the (5x+6). After that, the parenthesis should be gone. Then, move all the x values to one side, and the constants to the other. Then, solve as you normally would.
Original Statement: If x = 3, then x^2 = 9 (true)
Converse: If x^2 = 9, then x = 3 (false; this is half the story and x = -3 must be included)
Since the converse isn't completely true, we can't combine the two statements to get a biconditional.
