The universal shape of every quadratic.
A quadratic equation is any polynomial equation of degree 2. Its standard form is $ax^2 + bx + c = 0$, where $a$, $b$, and $c$ are constants, and $a \neq 0$. The coefficient $a$ is the leading coefficient, $b$ is the linear coefficient, and $c$ is the constant...
↳ Always rearrange a quadratic into $ax^2 + bx + c = 0$ before solving.
Solutions are called roots.
The solutions or roots of a quadratic equation are the values of $x$ that make the equation true. Graphically, these are the points where the parabola $y = ax^2 + bx + c$ crosses the $x$-axis. A quadratic equation can have two real roots, one real root...
↳ Roots are the x-intercepts of the parabola.
Break it down to zero.
↳ Factoring works best when the equation has simple integer roots.
Quadratic equations are polynomial equations of degree 2, expressed in the standard form $ax^2 + bx + c = 0$. They can be solved using factoring, completing the square, or the quadratic formula, with the discriminant det...

17 questions laddered from warm-up to topper-level, each with an explanation. A taste:
What is the standard form of a quadratic equation?
Beginner$ax^2 + bx + c = 0$
A quadratic equation is a polynomial equation of degree 2, so its standard form is $ax^2 + bx + c = 0$ where $a \neq 0$.
In the quadratic equation $3x^2 - 5x + 2 = 0$, what is the value of $a$?
Beginner3
In the standard form $ax^2 + bx + c = 0$, $a$ is the coefficient of $x^2$, which is 3 here.
Which of the following is a quadratic equation?
Beginner$x^2 + 3x - 1 = 0$
A quadratic equation must have degree 2. Only $x^2 + 3x - 1 = 0$ fits that form.
What is the discriminant of the quadratic equation $x^2 - 4x + 4 = 0$?
Intermediate0
The discriminant is $b^2 - 4ac$. Here $a=1$, $b=-4$, $c=4$, so $(-4)^2 - 4(1)(4) = 16 - 16 = 0$.
