Pls help struggling to help ny daughter the question is If the square number of a positive is increased by 3 times the number, the result is 54.find the number
\n" ); document.write( "

Let the number be N
\n" );
document.write( "Then we get: 
\n" );
document.write( " ------ Subtracting 54 from both sides
\n" );
document.write( "(N - 6)(N + 9) = 0 ------ Factoring TRINOMIAL on left
\n" );
document.write( "N - 6 = 0     OR      N + 9 = 0
\n" );
document.write( "N, or number =      OR       N = - 9 (ignore as this is NEGATIVE) \n" );
