\n" ); document.write( "Hi
\n" ); document.write( "Solving
\n" ); document.write( "(4x+9)(15x^2-7x-2) =0 |the concept is finding products = 0 to solve for x
\n" ); document.write( "factoring further:
\n" ); document.write( "factoring the (15x^2-7x-2)portion: factoring: expressing as 2 products..
\n" ); document.write( "In this case: (_x 1)(_x 2)|the hint here is the -7x middle term
\n" ); document.write( " (4x+9)(5x + 1)(3x - 2)= 0 |strategically placing the 5 and 3 & ± works
\n" ); document.write( " Note:SUM of the inner product(3x) and the outer product(-10x) = -7x
\n" ); document.write( "(4x+9)(5x+1)(3x -2)= 0 |NOW we are prepared to solve for x(s)
\n" ); document.write( "(4x+9)= 0 x = -9/4
\n" ); document.write( "(5x+1)= 0 x = -1/5
\n" ); document.write( "(3x -2)= 0 x = 2/3
\n" ); document.write( "Solution set is x = {-9/4,-1/5,2/3} \n" ); document.write( "
\n" );
