Algebra.Com's Answer #19020 by mukhopadhyay(490)![]() ![]() ![]() You can put this solution on YOUR website! x^2=12 + 5x \n" ); document.write( "=> x^2-5x-12 = 0 \n" ); document.write( "Per quadratic formula, roots of ax^2+bx+c are \n" ); document.write( "x=[-b+sqrt(b^2-4ac)]/2a and x=[-b-sqrt(b^2-4ac)]/2a \n" ); document.write( "In this example, a=1, b=-5, and c=-12 \n" ); document.write( "So, x= [5+sqrt(25+48)]/2 and x= [5-sqrt(25+48)]/2 \n" ); document.write( "=> x = [5+sqrt(73)]/2 and x = [5-sqrt(73)]/2 \n" ); document.write( " |
