Best ResponseYou've already chosen the best response.0We can now write: x^2 +3 = X + 5 which can also be written as: x^2  x  2 = 0 Do you agree? Or have you just went to the "looking around mode?"

Best ResponseYou've already chosen the best response.0(x2)(x+1) = 0 x=2 x=1 Now solve for y using the values found for x y= x +5 y=1 +5=4 y=2 + 5 =7 Now insert in first equation: y = x^2 + 3 y= 2^2 + 3 = 7 y= (1)^2 + 3 = 4 (2,7), (1,4)
