if x + y + z = 1 and x^2 + y^2 + z^2 = 3, then find the value of xy + xz + yz.
if x + y + z = 1 and x^2 + y^2 + z^2 = 3, then find the value of xy + xz + yz.
Hint: Expand (x + y + z)^2 first and compare left and right sides of the equation.

Jack wrote the following: (x+1)^2 - (x+2)(x-3) = x^2 + 2x+1-x^2-x-6 = x-5.
Jack wrote the following: (x+1)^2 - (x+2)(x-3) = x^2 + 2x+1-x^2-x-6 = x-5.
What mistakes did he make? write a correct simplification and explain how to avoid making this error.
