Evaluate (-2x)^2 and -2x^2 when x = 3.\r \n" ); document.write( "\n" ); document.write( "If x = 3, then replace x with 3 and simplify.\r \n" ); document.write( "\n" ); document.write( "(-2(3))^2 = (-6)^2 = 36\r \n" ); document.write( "\n" ); document.write( "===========================================\r \n" ); document.write( "\n" ); document.write( "For the next question, notice that there is no parentheses. This means that only the x value is squared and then the product is multiplied by -2.\r \n" ); document.write( "\n" ); document.write( "-2(3)^2 = -2(9) = -18\r \n" ); document.write( "\n" ); document.write( "Is this clear? \n" ); document.write( " \n" ); document.write( " |
