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.
