You can put this solution on YOUR website!
a(a − x) + 4b(x − 4b) = 0.
\n" ); document.write( "This is my solution am i on the right track:
\n" ); document.write( "a^2-ax+4bx-16b^2=0 (right)\r
\n" ); document.write( "\n" ); document.write( "(4b-a)x = 16b^2-a^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(4b-a)x = (4b-a)(4b+a) , since a is not equal to 4b (4b-a is not 0)\r
\n" ); document.write( "\n" ); document.write( "x = 4b+a\r
