What is the shortcut to find the roots of a quadratic equation?

2 Answers

1. 1) a+b+c=0 then the roots are 1 and c/a. Example: 33×2−41x+8=0 has 1 and 8/33 as solutions.
2. 2) b=a+c then the roots are −1 and −c/a. Example: 1793×2+2016x+223 has −1 and −223/1793 as roots.
3. 3) for x2+bx+c=0 I test the divisors of c. If one of them say α is a root then c/α is a root.

Is quadratic equations tough?

‘ Actually, difficult quadratic problems have little to do with intuition and a lot to do with understanding how numbers work. To solve a quadratic equation, you need to find the two factors that add up to give the middle term and multiply to give the product of the constant term and co-efficient of x^2.

How do I factor a quadratic equation?

Identities for Factoring Quadratics

1. Step 1: Divide both the sides of quadratic equation ax2 + bx + c = 0 by a.
2. Step 2: Subtract c/a from both the sides of quadratic equation x2 + (b/a) x + c/a = 0.
3. Step 3: Add the square of (b/2a) to both the sides of quadratic equation x2 + (b/a) x = -c/a.
