Please help me solve this equation. \n" ); document.write( "(3+2 sqrt 2)(1+ sqrt 2) \n" ); document.write( "but this is not an equation, perhaps they want you to FOIL this and simplify \n" ); document.write( "3 + 3sqrt(2) + 2sqrt(2) + 2(2) \n" ); document.write( "which is \n" ); document.write( "7 + 5sqrt(2) \n" ); document.write( ": \n" ); document.write( "Comment: \"Thank you, do you mind showing me how you got that answer.\" \n" ); document.write( "I am ashamed to see I made a mistake here, although I got the correct answer \n" ); document.write( " will try to correct it step-by-step \n" ); document.write( ": \n" ); document.write( "To multiply these two factors we use the FOIL method which stands for \n" ); document.write( "First; Outer, Inner, Last \n" ); document.write( ": \n" ); document.write( "Multiply \n" ); document.write( "First terms: 3 * 1 = 3 \n" ); document.write( "Outer terms: 3 * sqrt(2) = 3sqrt(2) \n" ); document.write( "Inner terms: 2sqrt(2) * 1 = 2sqrt(2) \n" ); document.write( "Last terms: sqrt(2) * 2sqrt(2) = 2(2) \n" ); document.write( "Which gives us \n" ); document.write( "3 + 3sqrt(2) + 2sqrt(2) + 4 \n" ); document.write( "Combine like terms \n" ); document.write( "3sqrt2) + 2sqrt(2) = 5sqrt(2) \n" ); document.write( "3 + 4 = 7 \n" ); document.write( "so we have \n" ); document.write( "7 + 5sqrt(2)\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
