step 1 - distributive property on the left to get
\n" ); document.write( "(i) $\"2x%5E2+-+x+=++2x%5E2+%2B+5x+-+12\"$
\n" ); document.write( "step 2 - simplify to get
\n" ); document.write( "(ii) $\"0+=+6x+-+12\"$
\n" ); document.write( "step 3 - solve for x to get
\n" ); document.write( "(iii) $\"x+=+2\"$
\n" ); document.write( "checking, we get
\n" ); document.write( "2(2*2-1) = 2*2^2+5*2-12
\n" ); document.write( "2(3) = 16+10-12
\n" ); document.write( "6 = 6
