Answer:
Examples of Quadratic Equation
A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. One absolute rule is that the first constant "a" cannot be a zero.
Standard Form Equations
Here are examples of quadratic equations in the standard form (ax² + bx + c = 0):
6x² + 11x - 35 = 0
2x² - 4x - 2 = 0
-4x² - 7x +12 = 0
20x² -15x - 10 = 0
x² -x - 3 = 0
5x² - 2x - 9 = 0
3x² + 4x + 2 = 0
-x² +6x + 18 = 0
Here are examples of quadratic equations lacking the linear coefficient or the "bx":
2x² - 64 = 0
x² - 16 = 0
9x² + 49 = 0
-2x² - 4 = 0
4x² + 81 = 0
-x² - 9 = 0
3x² - 36 = 0
6x² + 144 = 0
Here are examples of quadratic equations lacking the constant term or "c":
x² - 7x = 0
2x² + 8x = 0
-x² - 9x = 0
x² + 2x = 0
-6x² - 3x = 0
-5x² + x = 0
-12x² + 13x = 0
11x² - 27x = 0
