Algebra.Com's Answer #188097 by unlockmath(1688)![]() ![]() You can put this solution on YOUR website! Hello, \n" ); document.write( "Let's set up -x will represent a negative integer and -x+2 will represent the next negative integer. Now we can set up our equation as: \n" ); document.write( "(-x)^2 + (-x+2)^2=100 Rewrite this as: \n" ); document.write( "x^2+x^2-4x+4=100 Subtract 100 from both sides to be: \n" ); document.write( "x^2+x^2-4x-96=0 Combine like terms will result in: \n" ); document.write( "2x^2-4x-96 Factor out a 2 will be: \n" ); document.write( "2(x^2-2x-48)=0 This can be fractored as: \n" ); document.write( "2(x-8)(x+6)=0 Now we know that: \n" ); document.write( "x=8 \n" ); document.write( "x=-6 \n" ); document.write( "8 works as the answer so the negative integers are -8 and -6. \n" ); document.write( "Square both of those and you'll see it adds up to 100. \n" ); document.write( "Make sense? \n" ); document.write( "RJ \n" ); document.write( "Check out a new math book at: \n" ); document.write( "www.math-unlock.com \n" ); document.write( " |
