Algebra.Com's Answer #403177 by sachi(548)![]() ![]() You can put this solution on YOUR website! x^2 + 2x - 15 = 0 \n" ); document.write( "or x^2 + 5x-3x - 15 = 0 \n" ); document.write( "or x[x+5]-3[x+5]=0 \n" ); document.write( "or [x+5][x-3]=0 \n" ); document.write( "or x=-5 or 3 \n" ); document.write( "new roots are -1/5 & 1/3 \n" ); document.write( "so the eqn is x^2-x[-1/5+1/3]+{-1/5}*1/3 \n" ); document.write( "or x^2-2x/15-1/15=0 \n" ); document.write( "or 15x^2-2x-1=0 \n" ); document.write( "ans \n" ); document.write( " |
