Question1. Calculate $5^{2}+9$.
2. Factor $9 x^{2}-4$.
3. Complete the square for $x^2+3x=18$.

Studdy Solution
Calculate the value of the right side of the equation.
$$\left(X+\frac{3}{2}\right)^{2} = \frac{72}{4} + \frac{9}{4} = \frac{81}{4}$$So, the equation in completed square form is $\left(X+\frac{3}{2}\right)^{2} = \frac{81}{4}$.
