So I was helping my sister on homework and there was this problem:
2 abs(2x + 4) +1 > or equal to -3
teacher told her to ignore the -3 and just set it equal to zero.
Soo should you? This question got me confused. can't you just go about solving, bringing the 1 to the left and then dividing by 2?
EDIT: when I do it I get interval notaion from -3 to 3
and with the zero thing i get -2.5 to 2.5
