Question

Complete the squarex^2-15x+2=0

Answer 1

`\begin{gathered} x^2-15x+2=0 \\ x^2-15x+2-2=-2 \\ x^2-15x=-2 \\ 2ab=-15 \\ 2\cdot(1)\cdot b=-15 \\ b=(-15)/(2\cdot1) \\ b=(-15)/(2) \\ x^2-15x+((-15)/(2))^2=-2+((-15)/(2))^2 \\ \text{the number to complete the square is }(-15)/(2) \end{gathered}`
