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

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
