Algebra.Com's Answer #614509 by addingup(3677)![]() ![]() You can put this solution on YOUR website! (x − 1)2 ≥ 4 Multiply on left \n" ); document.write( "2x-2 ≥ 4 Add 2 on both sides \n" ); document.write( "2x ≥ 6 Divide both sides by 2 \n" ); document.write( "x ≥ 3 And now we write it in interval form. We want to say that x is equal or greater than 3: \n" ); document.write( "-------------- \n" ); document.write( "[3,∞) \n" ); document.write( "------------ \n" ); document.write( "The bracket on the left means that 3 is INCLUDED, because the problem says that x is equal or greater than. If the problem said that x was greater than, then we would use a parenthesis. So, if it was x > 3 we would write it (3,∞)\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
