Algebra.Com's Answer #640269 by Timnewman(323)![]() ![]() You can put this solution on YOUR website! hi dear, \n" ); document.write( "To factorize x²+9x+18, \n" ); document.write( "multiply the last term with the fist term,i.e x²*18=18x². \n" ); document.write( "Find two number such that their product is 18x² and their sum gives 9x (i.e the second term); \n" ); document.write( "Replace the the middle term(9x) with the sum of the the two numbers found.then group the expression by the use of bracket nd then fctorize. \n" ); document.write( "HERE IS THE WORKING.: \n" ); document.write( "6x*3x=18x² \n" ); document.write( "6x+3x=9x \n" ); document.write( "replace the middle term with 6x+3x in the given expression \n" ); document.write( "(x²+6x)+(3x+18) \n" ); document.write( "factor each bracket \n" ); document.write( "x(x+6)+3(x+6) \n" ); document.write( "then the factors \n" ); document.write( "(x+3)(x+6) \n" ); document.write( " --TIM \n" ); document.write( " |
