Q. Rewrite the function by completing the square.\newlinef(x)=x210x+44 f(x) = x^2 - 10x + 44 , f(x)=(x+)2+ f(x) = (x + \square)^2 + \square
  1. Step 11: Start with the function: We start with the function f(x)=x210x+44f(x) = x^2 - 10x + 44. To complete the square, we need to form a perfect square trinomial from the quadratic and linear terms. This involves finding a value that, when added and subtracted to the function, completes the square.
  2. Step 22: Find the value to complete the square: The coefficient of xx is 10-10. To complete the square, we take half of this coefficient, square it, and add it to and subtract it from the function. Half of 10-10 is 5-5, and (5)2(-5)^2 is 2525.
  3. Step 33: Add and subtract to complete the square: We add and subtract 2525 inside the function to complete the square. This gives us f(x)=x210x+25+4425f(x) = x^2 - 10x + 25 + 44 - 25.
  4. Step 44: Rewrite the function as a perfect square trinomial: Now we can rewrite the function as a perfect square trinomial plus a constant. The function becomes f(x)=(x5)2+19f(x) = (x - 5)^2 + 19.
  5. Step 55: Final result: We have successfully completed the square. The function f(x)f(x) is now written as f(x)=(x5)2+19f(x) = (x - 5)^2 + 19, which is the completed square form of the original function.
