Q. Complete the square. Fill in the number that makes the polynomial a perfect-square quadratic.t2−20t+____
Identify Coefficients: Identify the coefficients of the polynomial t2−20t+_ to compare with the standard quadratic form ax2+bx+c. a=1 (coefficient of t2) b=−20 (coefficient of t) c=? (the number we need to find)
Calculate Completing Square Value: To complete the square, we need to add (2b)2 to the polynomial. In this case, b=−20. Calculate (−20/2)2 to find the value that completes the square. (−20/2)2=(−10)2=100
Complete the Square: The number that completes the square for the polynomial t2−20t+_(_\\_\) is 100. So, the polynomial becomes a perfect-square quadratic: t2−20t+100.
