- Standard Form Equation: f(x) = ax² + bx + c
So firstly, since (0,5) is one of our values we can plug it into the standard form equation to solve for the c variable (since 0 will cancel out the a and b variable):

Now we know that the value of c is 5. Next, plug in (-1,12) into the standard form equation and simplify (remember to also plug in 5 for the c variable):

Next, plug (2,15) into the standard form equation and simplify:

Now, with our last two simplified equations we will create a system of equations:

Now, I will be using the elimination method with this system. With the system, add up the equations together and you will get:

From here, we can solve for the a variable. With it, just divide both sides by 3:

Now that we know the value of a, plug it into either equation to solve for the b variable:

<h2>Answer</h2>
Putting all of our obtained values together, your final answer is:

This problem calls for application of the distributive rule for multiplication.

Answer:
7 x − y = 17
Step-by-step explanation:
Apply the distributive property.
y + 3 = 7 x+ 7 ⋅ − 2
Multiply 7 by − 2 .
y + 3 = 7x − 14
Rewrite the equation with the sides flipped.
7 x − 14 = y + 3
Move all terms containing variables to the left side of the equation.
Subtract y from both sides of the equation.
7x−14−y=3
Move -14.
7x−y−14=3
