The product of two consecutive even integers plus their sum is 98.Find the numbers. \n" ); document.write( "let the two consecutive even integers are a,a+2 \n" ); document.write( "atq \n" ); document.write( "a*(a+2)+a+(a+2)=98 \n" ); document.write( "or a^2+2a+2a=2=98 \n" ); document.write( "or a^2+4a-96=0 \n" ); document.write( "or a^2+12a-8a-96=0 \n" ); document.write( "or a(a+12)-8(a+12)=0 \n" ); document.write( "or (a+12)(a-8)=0 \n" ); document.write( "or a=-12 or 8 \n" ); document.write( "so the pairs of onsecutive even integers are -12 & -10 or 8 & 10 \n" ); document.write( " \n" ); document.write( " |
