No, this is not a right triangle because no of the sides form a 90 degree angle.

Which two values of x are roots of the polynomial below?<br><br> x2 - 11x + 13
swat32

<u>Answer-</u>

<em>The values of x, which are the roots of the polynomial are </em>

\dfrac{11+ \sqrt{69}}{2},\ \dfrac{11- \sqrt{69}}{2}

<u>Solution-</u>

The given polynomial,

=x^2 - 11x + 13

We know that,

x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}

Here,

a = 1, b = -11, c = 13

Putting the values,

x=\dfrac{-(-11)\pm \sqrt{(-11)^2-4\times 1\times 13}}{2\times 1}

=\dfrac{11\pm \sqrt{121-52}}{2}

=\dfrac{11\pm \sqrt{69}}{2}

\therefore x=\dfrac{11+ \sqrt{69}}{2},\ \dfrac{11- \sqrt{69}}{2}
