Algebra.Com's Answer #81679 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! the product of two consecutive positive integers is 306. we need to find the integers. \n" ); document.write( ": \n" ); document.write( "Let the two integers = x, (x+1) \n" ); document.write( ": \n" ); document.write( "The product: \n" ); document.write( "x(x+1) = 306 \n" ); document.write( ": \n" ); document.write( "x^2 + x = 306 \n" ); document.write( ": \n" ); document.write( "x^2 + x - 306 = 0 \n" ); document.write( ": \n" ); document.write( "An easy way to find the factors, we know the two factors differ by 1 \n" ); document.write( "Find the square root of 306 on a calc. \n" ); document.write( "One factor is above this value and one is below. \n" ); document.write( "This would be: \n" ); document.write( "(x+18)(x-17) = 0 \n" ); document.write( "x = +17, -18 \n" ); document.write( "It wants the positive integers, so our solution will be: \n" ); document.write( "x = 17 \n" ); document.write( " |
