x = -b plus or minus the square root of (b^2 - 4ac) all divided by 2a. Used for quadratic equations where you can't factor. the equation is ax^2 + bx + c.
The best method of solving a quadratic. When your equation is in the standard form of ax² + bx + c = 0, x = (-b ± √b² - 4ac) / 2a. It is far superior to both factoring and completing the square. The equation may look difficult, but all you have to do is plug in the coefficients and simplify!
A: I had to use the quadratic formula to solve that tricky problem.
B: Why didn't you just do that in the first place?
Simply the most useless maths topic ever. i dont think ill ever be at the shops, looking to buy $2 of bananas and for some reason need to calculate where the bloody parabola is meant to go on the x and y axis. useless. id rather stick my nuts under
Teacher: Okay guys, time to continue on with your quadratics work from yesterday.
Me: fuck off u old wrinkly cunt.
