Algebra.Com's Answer #39458 by oberobic(2304)![]() ![]() ![]() You can put this solution on YOUR website! The rules of precedence require you to first do the exponentiation, so you must first solve (a-b)^2.\r \n" ); document.write( "\n" ); document.write( "Using the distributive property, (a-b)*(a-b) = a^2 - 2ab + b^2.\r \n" ); document.write( "\n" ); document.write( "Then you substitute into your original equation: \n" ); document.write( "4(a^2 - 2ab + b^2) + 7(a + b).\r \n" ); document.write( "\n" ); document.write( "That gives you 4a^2 - 8ab + 4b^2 + 7a + 7b. \n" ); document.write( " \n" ); document.write( " |
