Problem 3
Answer: y = x^2 - 7x + 10
----------
Work Shown:
Use either the FOIL method, distributive property, or the box method to get the following
(x-2)*(x-5) = x^2 - 5x - 2x + 10 = x^2 - 7x + 10
==========================================
Problem 4
Answer: y = x^2 - x - 6
----------
Work Shown:
Same idea as problem 3 above
(x-3)(x+2) = x^2+2x-3x-6 = x^2 - x - 6
