## What are the roots of quadratic equation x2 3x 1 0?

If x^2 + 3x + 1 0 , then the roots of the equation are x -3 xb1 u221a(m)/2 .

## How do you find the roots?

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) 0, and solve the equation, ax2 + bx + c 0.

## How do you find the Y intercept and roots?

The x-intercepts are the roots. As for the y-intercept, it is the value of y when x 0. Therefore, the y-intercept of a polynomial is simply the constant term, which is the product of the constant terms of all the factors.

## What is the answer of x2 3x 10 0?

George C. So x2u22123xu2212100 has roots x5 and xu22122 .

## What is the root of x2 3x 10 0?

Roots are 4 and 3.

## What is the best method to use in finding the solutions of x2 3x 10 0?

Factoring is definitely the easier method, and you want to make two single variable equations multiply to x^2-3x-100. Therefore we can use the backwards method of the FOIL (First, Outer, Inner, Last) method. Since a1, you need to have two numbers that add to your b value, -3, but multiply to get your c value, -10.
