What are the approximate values of the non-integral roots of the polynomial equation? –5.57 –1.95 0.21 1.27 4.73

Option 4 and 5.

Step-by-step explanation:

Consider the given polynomial equation is

We need to find approximate values of the non-integral roots of the polynomial equation.

Find factor form.

For x=-2 the value of parenthesis is 0. It means (x+2) is a factor of parenthesis.

Divide the parenthesis by (x+2). After division remainder is 0 and quotient is , so the factor form is

Equate the factor form equal to 0, to find the roots.

           .... (1)

Quadratic formula for is

In (1), a=1, b=-6, c=6. Using quadratic formula we get

The approximate values of the non-integral roots of the polynomial equation are 4.73 and 1.27.

Therefore, the correct options are 4 and 5.

can i get the link to the assignment?

step-by-step explanation:

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
