document.write( "Question 899375: Hey, how would you solve:
\n" ); document.write( "3.5*10^-6(15-s)^2=2.5*10^-6*s^2
\n" ); document.write( "i know the answer is 0.3s^2 - 30s + 225 = 0
\n" ); document.write( "but how do i get here?
\n" ); document.write( "Thanks, its appreciated,

$\"3.5%2A10%5E%28-6%29%2815-s%29%5E2=2.5%2A%2810%5E-6%29%2As%5E2\"$
\n" ); document.write( "Divide both sides by $\"10%5E%28-6%29\"$
\n" ); document.write( " $\"3.5%2A%2815-s%29%5E2=2.5%2As%5E2\"$
\n" ); document.write( " $\"%287%2F2%29%2815-s%5E2%29=%285%2F2%29s%5E2\"$
\n" ); document.write( "Multiply both side by $\"2\"$
\n" ); document.write( " $\"7%2815-s%29%5E2=5s%5E2\"$ }
\n" ); document.write( " $\"7%28225-30s%2Bs%5E2%29=5s%5E2\"$
\n" ); document.write( " $\"1575-210s%2B7s%5E2=5s%5E2\"$
\n" ); document.write( " $\"highlight%282s%5E2-210s%2B1575=0%29\"$
\n" ); document.write( "That's not the same answer as the one you stated.
\n" ); document.write( "Your given answer would be (multiplying the equation by $\"20%2F3\"$ to match the leading coefficient),
\n" ); document.write( " $\"2s%5E2-200s%2B1500=0\"$ \r
