How do I make a perfect square. Sorry my addition key isn't working
y^2-18y plus______
To make a perfect square, you need to complete the square by finding the missing term that completes the square. In this case, the missing term is denoted by "______".
To create a perfect square, you need to take half of the coefficient of the y-term and square it. The coefficient of the y-term in this case is -18y.
Therefore, we need to compute (-18y)/2 and square it.
(-18y)/2 = -9y
(-9y)^2 = 81y^2
So the missing term that completes the square is 81y^2.
Thus, the expression y^2 - 18y + 81y^2 is a perfect square.
