The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√ …

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 …

So if we look at the quadratic equation that we need to solve here, we can just pattern match. We're dealing with q's, not x's, but this is the same general idea.

Solve quadratic equations using the quadratic formula. For example, solve -9x+10x²+8=14.

We've seen linear and exponential functions, and now we're ready for quadratic functions. We'll explore how these functions and the parabolas they produce can be used to solve real-world problems.

Practice Number of solutions of quadratic equations Get 3 of 4 questions to level up!

And actually, I'll solve it twice using the quadratic formula to show you that as long as we manipulated this in the valid way, the quadratic formula will give us the exact same roots or the exact same …

Use the quadratic formula to solve the equation, negative x squared plus 8x is equal to 1. Now, in order to really use the quadratic equation, or to figure out what our a's, b's and c's are, we have to have our …

So I've noticed something about factoring a quadratic equation. I'm not sure if this applies to all quadratic equations, but when you put one in the form of ax^2+bx+c=0, factor it, and then multiply a and the …

The formula is the easiest way to solve the quadratic equation. It works for all types of equations and can even be used to find out if the equation has a real solution or not.
