The quadratic formula is used to solve for in equations taking the form of a quadratic equation, ++=0. quadratic formula: =−±√−/ solve for in the expression using the quadratic formula. +−6.1=0. use at least three significant figures in each answer.

Using the quadratic formula

The answer to the equation using at least three significant figures is:

Step-by-step explanation:

The quadratic formula is used to solve polynomials of second degree.

We have a polynomial of second degree to be resolved with the quadratic formula:

(Eq. 1)

We know the quadratic formula is:

(Eq. 2)

To resolve the quadratic formula we need the a, b and c coefficients, we can find these coefficients in the equation 1.

a: Coefficient that accompanies

b: Coefficient that accompanies

c: Independent term

With this information and the equation (1). We know the values of a, b and c

Now, we can replace these terms in the quadratic formula (Eq. 2)

The first root will be found using the positive sign before the square root:

The second root will be found using the negative sign before the square root

:

c. side angle side. u shares the same sides
