Quadratic Equations

Nature Of The Roots Of A Quadratic EquationThe nature of the roots depends on the value of b2 – 4ac. bx2 – 4ac is called the discriminant of the quadratic equation ax2 + bx + c = 0 and is generally, denoted by D. ∴ D = b2 – 4ac If D > 0,…

Solving A Quadratic Equation By Factoring Since, 3x2 – 5x + 2 is a quadratic polynomial; 3x2 – 5x + 2 = 0 is a quadratic equation. Also, 3x2 – 5x + 2 = 3x2 – 3x – 2x + 2 = 3x (x – 1) – 2(x – 1) = (x – 1) (3x – 2) In the same way : 3x2 – 5x…

Solving Factorable Quadratic EquationsA quadratic equation is a polynomial equation of degree two. The standard form is ax² + bx + c = 0.There’s no magic to solving quadratic equations. Quadratic equations can be solved by factoring and…
