# Wrong Answers you gave to Two Students

**Question description**

You have two wrong answers you got paid for:

Question 1: "Algebra Question Asked"

1*0 is NOT 1, 1*0 = 0!!!!

1+1+1....x 0+1 = you said 30, however, anything x 0 = 0, then if you add 1, the answer is 1, not 30.

Question 2: "I need help in solving this equation"

The second equation you got wrong was 4 * (-2)^2 - 1/(-2)^2

= 4*4 - ( 1/4)

= 16 - (1/4)

= (16*4 -1)/4

= 63/4

The 1/4 is NOT separate!!! The 4x^2-1 is the NUMERATOR! The correct answer is [4(-2)^2 -1]/4 = 15/4, make sure you account for both problems in case the student does not put the numerator in parenthesis. If they don't specify, do it both ways and show the difference, so the student knows.
