Result: 1 2/3 : 4 3/8 = 821 ≅ 0.3809524 ... subtraction fractions: 2/3 - 1/2 • multiplying a fraction by another fraction - multiplication: 7/8 * 3/9 ... multiplying a fraction by a whole number: 6 * 3/4
In a standard binomial equation: ax² + bx + c = 0
To complete the square; divide the middle coefficient "b" in half and square it to find "c".
(-5/2)² = 25/4
x² - 5x + 25/4 = 25/4
completes the square:
(x - 5/2)² = 25/4
