Answer:
You need to add 1/36th to both sides of the equation, giving you the expression
Which can be expressed as:
Step-by-step explanation:
We need to add a term that is the the square of half the coefficient of the second term.
Let's check the answer by expanding:
Which verifies the answer.
F(5) = 3x(5)^2 - 5 = 3x25 - 5 = 75 - 5 = 70;
f(4) = 3x(4)^2 - 5 = 3x16 - 5 = 48 - 5 = 43;
f(x) + g(x) = 3
f(4) = 3x(4)^2 - 5 = 3x16 - 5 = 48 - 5 = 43;
f(x) + g(x) = 3
