Kumar explores quadratic functions, focusing on converting a given equation into standard form. The video demonstrates expanding the equation and provides an exercise to convert it into vertex form. Techniques like completing the square and finding the axis of symmetry are suggested for this conversion.

What is the standard form of a quadratic equation?

• y = ax^2 + bx + c

• y = a(x - h)^2 + k

• y = a(x - p)(x - q)

• y = ax + b

What is the given quadratic equation in the video?

• y = 3x^2 - 3x + 2

• y = 3x - 3x + 2

• y = x^2 + 3x + 2

• y = 3(x - 1)(x + 2)
