The essential definition you must know.
A quadratic equation in the variable $x$ is an equation of the form $ax^2 + bx + c = 0$, where $a$, $b$, $c$ are real numbers and $a \neq 0$. The term $ax^2$ is the quadratic term, $bx$ is the linear term, and $c$ is the constant term.
↳ A quadratic equation is a second-degree polynomial equation set to zero.
The universal format for all quadratics.
Any quadratic equation can be rewritten in this standard form by moving all terms to one side and simplifying. This form is the starting point for solving by factorization, completing the square, or using the quadratic formula.
↳ Always rewrite a quadratic equation in the form $ax^2 + bx + c = 0$ before solving.
Spot a, b, and c quickly.
For the equation $2x^2 - 3x + 5 = 0$, the coefficients are:
↳ Always note the signs: $b$ and $c$ include their signs.
Quadratic equations are second-degree polynomial equations of the form $ax^2 + bx + c = 0$. They can be solved by factorization or the quadratic formula, and the discriminant determines the nature of the roots. This kit...

18 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Which of the following is the standard form of a quadratic equation?
Beginner$ax^2 + bx + c = 0$
The standard form of a quadratic equation is $ax^2 + bx + c = 0$, where $a \neq 0$.
In the equation $2x^2 - 3x + 5 = 0$, what is the value of $a$?
Beginner2
In the standard form $ax^2 + bx + c = 0$, $a$ is the coefficient of $x^2$, which is 2.
Which of the following is a quadratic equation?
Beginner$x^2 + 2x + 1 = 0$
A quadratic equation has degree 2, so $x^2 + 2x + 1 = 0$ is quadratic.
What are the roots of the equation $x^2 - 5x + 6 = 0$?
Intermediate2 and 3
Factorizing: $x^2 - 5x + 6 = (x-2)(x-3) = 0$, so $x=2$ or $x=3$.
