document.write( "Question 257077: Find three consecutive even integers if the product of the second and third is eighty eight more than four times the first.\r
\n" );
document.write( "\n" );
document.write( "So I have (x+2)(x+4)= 4(x)+ 84. Then when I combine like terms I have x^2+2x-76. Is this correct? If so, how does it factor? \n" );

Algebra.Com's Answer #189052 by rajagopalan(174) You can put this solution on YOUR website! Solution \n" ); document.write( "you have (x+2)(x+4)= 4(x)+ 88. \n" ); document.write( "x^2+6x+8=4x+88 (not eighty four as u assumed) \n" ); document.write( "x^2+2x-80=0 \n" ); document.write( "x^2-8x+10x-80=0 \n" ); document.write( "x(x-8)+10(x-8)=0 \n" ); document.write( "(x+10)(x-8)=0 \n" ); document.write( "gives x=-10 or 8 \n" ); document.write( "take 8 as positive answer \n" ); document.write( "0thers are 10 and 12 obviously \n" ); document.write( "good day \n" ); document.write( "cheers \n" ); document.write( " |
