Algebra.Com's Answer #593798 by khai(18) You can put this solution on YOUR website! =[(x^2)(8x-64+x^2-8x)]/[x^2-5x+2x-10] \n" ); document.write( "=(2x^2-64)/(x^2-3x-10) \n" ); document.write( "0=(2x^2-64)/(x^2-3x-10) ----- because the question said that {x^2(8+x)(x-8)/(x+2)(x-5) is greater than and equal to 0} \n" ); document.write( "0=2x^2-64 ----- because zero times anything is zero \n" ); document.write( "64=2x^2 \n" ); document.write( "32=x^2 \n" ); document.write( "x= sqrt 32 or x= -sqrt 32 \n" ); document.write( "which is \n" ); document.write( "x= 5.657 or x= -5.657 \n" ); document.write( " \n" ); document.write( " |
