Algebra.Com's Answer #129536 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! 2(x+1)^2+14(x+1)+20=0\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Factor out the common factor of 2, or, better yet, divide both sides by 2: \n" ); document.write( "(x+1)^2+7(x+1)+10=0\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "This factors into \n" ); document.write( "((x+1) +5)*((x+1) + 2)=0 \n" ); document.write( "(x+6)(x+3)=0 \n" ); document.write( "x=-6 or x= -3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "I don't see the correct answer here. Did you copy the multiple choices correctly??? Also, there are other methods to solve this, in case I confused you with this solution.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "ALTERNATE SOLUTION (for anyone who did not understand the above solution!) \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "This trinomial factors into the product of two binomials: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "x= -6 or x = -3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Different method, same solution!! I KNOW this is correct!! The given answers are WRONG!!\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "R^2 \n" ); document.write( " |
