Algebra.Com's Answer #772141 by amarjeeth123(570) ![]() You can put this solution on YOUR website! We are given that the equation 3bx^2 + 6bx = ax + 2a has two solutions for x and \n" ); document.write( "the sum and the product of the roots are equal. \n" ); document.write( "The given equation can be rewritten as 3bx^2+(6b-a)x+(-2a)=0 \n" ); document.write( "The sum of the roots=(a-6b)/3b \n" ); document.write( "Product of the roots=(-2a)/3b \n" ); document.write( "Since both of them are equal we get,a-6b=-2a \n" ); document.write( "3a-6b=0 \n" ); document.write( "3a=6b \n" ); document.write( "a=2b \n" ); document.write( "b/a=1/2. \n" ); document.write( "Verification: \n" ); document.write( "Put b=1 and a=2 \n" ); document.write( "The equation becomes 3x^2+6x=2x+4 \n" ); document.write( "3x^2+4x-4=0 \n" ); document.write( "Sum of the roots=-4/3 \n" ); document.write( "Product of the roots=-4/3 \n" ); document.write( "Hence the solution is correct. \n" ); document.write( "b/a=1/2. \n" ); document.write( " |
