Completing the square with a number in front
WebFor example, completing the square with y = 𝑥 2 + 4𝑥 + 1 rearranges the equation to y = (𝑥 + 2) 2 – 3. y = 𝑥 2 + 4𝑥 + 1 and y = (𝑥 + 2) 2 – 3 are the same equation, just rearranged. Proof … WebCompleting the square just means adding the same number to both sides of the equation -- which, remember, doesn't change the value of the equation -- in order to create a perfect square. Start with the original equation: Put all of the terms on one side: Now we know that we have to add something to both sides in order to create a perfect square:
