Question

Formula to find roots to quadratic equation

Answer 1

Hey there!

General form Quadratic formula:
ax^2 + bx + c = 0

There are various ways for finding the roots of Quadratic Equation, which are as follows:

1. FACTORISATION

2. BY COMPLETING SQUARE METHOD.

3. BY QUADRATIC FORMULA**

** Quadratic formula
X = -b ± √D/2a

Where D = b^2 - 4ac

IF D > 1 : REAL & DISTINCT ROOTS
IF D = 1 : REAL & EQUAL ROOTS
IF D < 1 : NO REAL ROOTS (IMAGINARY NUMBER)

HOPE IT HELPED ^_^
