Checkpoint over completing the square/quad formula

Which of the following equations matches standard form of a quadratic?

• ax + by = c

• y = ax² + bx + c
• y = mx + b

What is this?

• This is the speed of light formula.
• This is the quadratic formula.
• This is the zero product property.
• This is scary.
