Answer:
A
Step-by-step explanation:
A) EA and ST
Given:
Polynomial 
To find:
The values of x.
Solution:

Quadratic equation formula:

Here
.
Substitute the values in the formula, we get




Option E and option F are the roots of the polynomial.
The values of x are
.
Since x=x, this is an isosceles right triangle. By the Pythagorean Theorem:
h^2=a^2+b^2 (the hypotenuse squared is equal to the sum of the squared sides)
5^2=x^2+x^2
25=2x^2
2x^2=25
x^2=25/2
x=√(25/2)
x=5/√2 now if we rationalize the denominator...
x=(5√2)/(√2√2)
x=(5√2)/2
