Algebra.Com's Answer #3461 by prabhjyot(165)![]() ![]() ![]() You can put this solution on YOUR website! sqrt(-5x+24)=6-X \n" ); document.write( "Squaring both sides\r \n" ); document.write( "\n" ); document.write( "-5x +24 = (6-x)^2 \n" ); document.write( "-5x =24 =x^2 +36 -12x \n" ); document.write( "x^2- 7x +12=0 \n" ); document.write( "Now solving for x \n" ); document.write( "step 1:Write down all the different ways to factor the constant coefficient (12) into two negative numbers: \n" ); document.write( "12 = ( -1)(-12 ) \n" ); document.write( "12 = ( -2)( -6 ) \n" ); document.write( "12 = ( -3)( -4 )\r \n" ); document.write( "\n" ); document.write( "(Order doesn’t matter. So (-3)(-4) is the same as (-4)(- 3).)\r \n" ); document.write( "\n" ); document.write( "Step 2: Now, for each possible factorization, add together the two factors. You’re looking for two that add up to the middle coefficient, which is –7. \n" ); document.write( "-1 – 12 = –13 \n" ); document.write( "-2 – 6 = –8 \n" ); document.write( "-3 – 4 = – 7 < --------------------------- found it!\r \n" ); document.write( "\n" ); document.write( "The factors which worked out were –3 and –4, so here’s how \n" ); document.write( "you factor the polynomial: \n" ); document.write( "(x – 3)(x – 4)\r \n" ); document.write( "\n" ); document.write( "So the solution to the equation is x=3,4 \n" ); document.write( " |
