SOLVING QUADRATICS BY COMPLETING THE SQUARE - KHAN ACADEMY
Web The 25/4 and 7 is the result of completing the square method. To factor the equation, you need to first follow this equation: x^ 2 + 2ax + a^2. In x^2 +5x = 3/4, The a^2 is missing. To figure out the a, you need to take the 5 and divide it by 2 (because 2ax), which becomes 5/2. a=5/2. Then you need to square it, (because a^2) which becomes 5^2/2^2.
