Segment AB is 7 units long. A(2, 3) , B(2, -4). After the segment is rotated 90 degrees clockwise around the origin, then translated 5 units up, how long is segment AB?

The quadratic formula helps you solve quadratic equations, and is probably one of the top five formulas in math.  We’re not big fans of you memorizing formulas, but this one is useful (and we think you should learn how to derive it as well as use it, but that’s for the second video!).

If you have a general quadratic equation like this:

ax2+bx+c=0ax^2+bx+c=0ax2+bx+c=0a, x, squared, +, b, x, +, c, =, 0

Then the formula will help you find the roots of a quadratic equation, i.e. the values of x x xx where this equation is solved.
