Q. What is the missing constant term in the perfect square that starts with x2+14x?
Identify values of a and b: Identify the values of a and b in the quadratic expression x2+14x+?.Here, a=1 (coefficient of x2) and b=14 (coefficient of x).
Find perfect square value: To complete the square, we need to find the value that makes the expression a perfect square. This value is found by taking (2b)2.Calculate (214)2 to find the missing constant term.
Calculate missing constant term: Perform the calculation: (214)2=(7)2=49.The missing constant term is 49.
