Question

So simplify the expression. x(y+z) - 2(xy)
Please explain the steps. Supposely the answer is
-xy+xz ????? I don't see how to get it.

Answer 1

How did the z get on the right side?

Answer 2

x(y+z) -2(xy)
must do a foil method
x times the quantity of y+z is xy + xz
-2 times the quantity of xy is -2xy

combine similar terms
xy - 2xy is -xy

the back to the equation
-xy + xz

since when you multiplied the x in (y+z) the result is xy + xz there the firs one is the xy so you just need to follow it
