You can put this solution on YOUR website!
I'm assuming your first = sign is actually a - sign. \r
\n" ); document.write( "\n" ); document.write( "Here you go:\r
\n" ); document.write( "\n" ); document.write( "x^(2)+4x+8-8x=29\r
\n" ); document.write( "\n" ); document.write( "Since 4x and -8x are like terms, add -8x to 4x to get -4x.
\n" ); document.write( "x^(2)-4x+8=29\r
\n" ); document.write( "\n" ); document.write( "Since 8 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 8 from both sides.
\n" ); document.write( "x^(2)-4x=-8+29\r
\n" ); document.write( "\n" ); document.write( "Add 29 to -8 to get 21.
\n" ); document.write( "x^(2)-4x=21\r
\n" ); document.write( "\n" ); document.write( "To set the left-hand side of the equation equal to 0, move all the expressions to the left-hand side.
\n" ); document.write( "x^(2)-4x-21=0\r
\n" ); document.write( "\n" ); document.write( "For a polynomial of the form x^(2)+bx+c, find two factors of c (-21) that add up to b (-4). In this problem 3*-7=-21 and 3-7=-4, so insert 3 as the right hand term of one factor and -7 as the right-hand term of the other factor.
\n" ); document.write( "(x+3)(x-7)=0\r
\n" ); document.write( "\n" ); document.write( "Set each of the factors of the left-hand side of the equation equal to 0.
\n" ); document.write( "x+3=0\r
\n" ); document.write( "\n" ); document.write( "Set each of the factors of the left-hand side of the equation equal to 0.
\n" ); document.write( "x-7=0\r
\n" ); document.write( "\n" ); document.write( "Since 3 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 3 from both sides.
\n" ); document.write( "x=-3\r
\n" ); document.write( "\n" ); document.write( "Since -7 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 7 to both sides.
\n" ); document.write( "x=7\r
\n" ); document.write( "\n" ); document.write( "The complete solution is the set of the individual solutions.
\n" ); document.write( "x=-3,7
\n" ); document.write( "
