Algebra.Com's Answer #402825 by Theo(13342)![]() ![]() You can put this solution on YOUR website! you have y = x^2 and you have y = 6x - 5 \n" ); document.write( "since they are both equal to y, then they are both equal to each other and you get x^2 = 6x - 5 \n" ); document.write( "subtract 6x and add 5 to both sides of this equation to get x^2 - 6x + 5 = 0 \n" ); document.write( "this a quadratic equation whose factors are (x-5) * (x-1) \n" ); document.write( "your equation becomes (x-5) * (x-1) = 0 \n" ); document.write( "since each of these factors can be set equal to 0, you get: \n" ); document.write( "x-5 = 0 and x-1 = 0 \n" ); document.write( "solve for x in both these equations to get x = 5 and x = 1 \n" ); document.write( " \n" ); document.write( " |
