Q. Rewrite the function by completing the square.f(x)=x2−12x−29, f(x)=(x+□)2+□
Given quadratic function: We start with the given quadratic function:f(x) = x2−12x−29Our goal is to rewrite this function in the form of (x+a)2+b.
Completing the square: First, we need to complete the square for the x2−12x part of the function. To do this, we find the value that needs to be added and subtracted to complete the square. This value is (2b)2, where b is the coefficient of x, which in this case is −12.(2−12)2=36
Adding and subtracting to complete the square: We add and subtract 36 inside the function to complete the square:f(x) = (x2−12x+36)−36−29
Factoring the quadratic expression: Now we factor the quadratic expression in the parentheses:f(x) = (x−6)2−36−29
Simplifying the function: Combine the constants to simplify the function: f(x)=(x−6)2−65
