  • Quadratic equation - Wikipedia
    In mathematics, a quadratic equation (from Latin quadratus ' square ') is an equation that can be rearranged in standard form as [1] a x 2 + b x + c = 0, ${\displaystyle a{x}^{2}+bx+c=0\phantom{\rule{0 167em}{0ex}},}$ where the variable x ${\displaystyle x}$ represents an unknown number, and a, b, and c represent known numbers, where a ≠ 0 (If a = 0 and b ≠ 0 then the equation is linear
  • The quadratic formula | Algebra (video) | Khan Academy
    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±√ (b²-4ac)) (2a) See examples of using the formula to solve a variety of equations Created by Sal Khan
  • 8. 4: The Quadratic Formula - Mathematics LibreTexts
    The goal of this section is to develop a formulaic shortcut that will provide exact solutions of the quadratic equation ax2 +bx+c = 0 We start by moving the constant term to the other side of the equation a x 2 + b x + c = 0 Quadratic equation a x 2 + b x = c Subtract c from both sides
  • Quadratic Formula -- from Wolfram MathWorld
    The quadratic formula gives the roots of a quadratic equation ax^2+bx+c=0 (1) with a!=0 as x= (-b+ -sqrt (b^2-4ac)) (2a) (2) An alternate form, valid when the denominator is nonzero, is given by x= (2c) (-b+ -sqrt (b^2-4ac)) (3) For a quadratic equation with leading coefficient 1, x^2+px+q=0, (4) the quadratic formula becomes the pq formula (Kucherenko 2007), x=-p 2+ -sqrt ( (p^2) 4-q) (5
