I will add + operators, because the equation is incomplete.

f(x) = x^2 + 2x + 3

To find the solution, complete a perfect square


f(x) = (x^2 + 2x + 3) -2 + 2
f(x) = (x^2 + 2x + 1) + 2
f(x) = (x + 1)^2 + 2

Answer: (x+1)^2 + 2

X:y=5:3 and x+y=56<br> what is the value off x-y
Rudiy27

x:y=5:3\to\dfrac{x}{y}=\dfrac{5}{3}\qquad\text{cross multiply}\\\\3x=5y\qquad\text{divide both sides by 3}\\\\x=\dfrac{5}{3}y\\\\\text{substitute to the equation} \ x+y=56\\\\\dfrac{5}{3}y+y=56\\\\\dfrac{5}{3}y+\dfrac{3}{3}y=56\\\\\dfrac{5+3}{3}y=56\\\\\dfrac{8}{3}y=56\qquad\text{multiply both sides by 3}\\\\8y=3\cdot56\qquad\text{divide both sides by 8}\\\\y=3\cdot7\\\\y=21\\\\\text{substitute the value of y to the equation}\ x=\dfrac{5}{3}y\\\\x=\dfrac{5}{3}\cdot21=5\cdot7=35


Answer:\ \boxed{x-y=35-21=14}
