Complete the square

Full solution

Q. Complete the square. Fill in the number that makes the polynomial a perfect-square quadratic.

\newline

f^2 - 30f + \_\_\_\_\_

Identify coefficients: Identify the values of $a$ , $b$ , and $c$ in the quadratic expression. $\newline$ Leading coefficient ( $a$ ): $1$ $\newline$ Coefficient of linear term ( $b$ ): $-30$ $\newline$ Constant ( $c$ ): $?$
Complete the square: Determine the value needed to complete the square. $\newline$ To complete the square for $f^2 - 30f$ , add $\left(-\frac{30}{2}\right)^2$ . $\newline$ Perfect square quadratic: $f^2 - 30f + \left(-\frac{30}{2}\right)^2$
Calculate missing value: Calculate $(-30/2)^2$ to find the missing value in $f^2 − 30f + \_\_\_$ . $\newline$ $(-30/2)^2$ $\newline$ $= (-15)^2$ $\newline$ $= 225$
