document.write( "Question 148923: I am having a terrible time solving this equation 4^2 - 4x = -3
\n" );
document.write( "It must be solved using the Indian method of first multiplying each term by 4. I have done that with the result of 16^2 - 16x = -12. The next step in this method is to add the square of the coefficient of the original x term to both sides, which results in 16^2 - 16x + 16 = -12 + 16. I have this correct, but cannot figure out how to complete the equation. How can I factor this equation, and then solve it.\r
