Answer:
Shown below
Step-by-step explanation:
I'll just remove f(x) because it's not necessary right now.
Square (x-1). Remember that squaring 2 value equations can use the equation [tex]x^{2} + 2xy + y^{2}[/tex]
Using the equation above, we get [tex]x^{2} - 2x + 1[/tex] , also can be found by foiling.
[tex]x^{2} + 2x + 1 + 2 = x^{2} +2x+3[/tex]
And just like that, we're done
