**Sum and product of roots SlideShare**

Quadratic Equations: Sum & Product of the Roots The roots of a quadratic equation are its solutions. Graphically, this is where the curve touches the x-axis. how to find error in runge kutta method one easy way to do it is to just bite the bullet and solve the equation and then find out sum and product of roots x1 and x2. Another is to note that for equations , b is the sum of roots and c is their product. that means looking at equation x^2+4x-3/2 = 0. sum is 4, product is -3/2.

## How To Find Equation Using Sum And Product Of Roots

2/03/2007 · The sum of all the roots is -2 that's the 2d coefficient. as quickly as I multiply all the roots jointly, i'll get 6 that's the consistent on the tip. an uncomplicated occasion: x^2-2x+a million=0 enable the roots be a and b. i comprehend from finding at that equation that a+b=2 and (a)(b)=a million a=a million, b=a million is the answer consequently the two roots are x=a million as a double

- So the product of the roots to your expression will be (3)/(4) = 3/4 If you didn't know that the sum was -b/2a and/or that the product was c/a then it is not terribly difficult to figure this out on your own.
- Quadratic equations are equations of the form ax 2 + bx + c = 0. A quadratic equation has two roots. These roots are found either by factorizing the quadratic equation or by using the formula (-b + root (b 2 – 4ac))/2a and (-b – root (b 2 – 4ac))/2a
- For a quadratic equation a^2 + bx + c = 0 where a ≠ 0. Sum of roots α + β = - b ÷ a Product of roots α X β = c ÷ a A quadratic equation can be written in the form x^2 - (sum of roots) x + (product of roots…
