We begin by finding the constant d that can be used to complete the square. d=(b2)2=(122)2=62=36 x2+12x+d=0+d⇒ x2+12x+36=0+36⇒ (x+6)2=36 √(x+6)2=±√36 x+6=6orx+6=−6x=0x=−12 The completing the square method could of course be used to solve quadra...
When you complete the square, make sure that you are careful with the sign on the numerical coefficient of the x-term when you multiply that coefficient by one-half. If you lose the sign from that term, you can get the wrong answer in the end because you'll forget which sign goes ...
Completing the square is a fairly nifty trick that pops up a decent bit in Calculus 2, particularly in taking integrals of trig functions. Since they need to be in the specific form of (x+a)^2, or some variation thereof. If a student didn’t know how to complete the square, they wo...
Example:Complete the square given the equation \(4x^2 + 4y^2 - 24x + 32y - 4 = 0\) 1) Do the squared terms have matching coefficients? Yes. So, we have a circle here. 2) Can we make the squared terms have a coefficient of 1?
