What is the quadratic form formula?
An equation that is quadratic in form can be written in the form au2+bu+c=0 where u represents an algebraic expression. In each example, doubling the exponent of the middle term equals the exponent on the leading term.
What is Sridharacharya quadratic formula?
Sridharacharya Formula is also known as the quadratic formula or Sridharacharya Method. Sridharacharya Method is used to find solutions to quadratic equations of the form ax2 + bx + c = 0, a ≠ 0 and is given by x = (-b ± √(b2 – 4ac)) / 2a. It is one of the main math formulas.
What is the formula of quadratic inequality?
Write the quadratic inequality in standard form: ax2 + bx + c where a, b and are coefficients and a ≠ 0. Determine the roots of the inequality. Write the solution in inequality notation or interval notation.
What is b2 4ac?
The quantity b2−4ac is called the discriminant of the polynomial. If b2−4ac < 0 the equation has no real number solutions, but it does have complex solutions. If b2−4ac = 0 the equation has a repeated real number root. If b2−4ac > 0 the equation has two distinct real number roots.
Who found quadratic formula?
The 9th-century Persian mathematician Muḥammad ibn Mūsā al-Khwārizmī solved quadratic equations algebraically. The quadratic formula covering all cases was first obtained by Simon Stevin in 1594. In 1637 René Descartes published La Géométrie containing special cases of the quadratic formula in the form we know today.
How is the ± related to the quadratic formula?
The ± indicates that the quadratic formula has two solutions. Each of these is referred to as a root. Geometrically, these roots represent the points at which a parabola crosses the x-axis. Thus, the quadratic formula can be used to determine the zeros of any parabola, as well as give the axis of symmetry of the parabola.
When did Brahmagupta write the quadratic formula?
The Indian mathematician Brahmagupta (597–668 AD) explicitly described the quadratic formula in his treatise Brāhmasphuṭasiddhānta published in 628 AD, but written in words instead of symbols.
