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

☝️☝️these are the examples of quadratic equations.
