Question

Solve the quadratic equation by using the quadratic formula. If the solutions are not real, enter NA.

Answer 1

By using the quadratic formula, the roots of the quadratic equation 2 · x² - 7 · x + 1 are represented by the irrational number x = (7 ± √41) / 4.

How to find the roots of quadratic equation by quadratic formula

For polynomials of the form a · x² + b · x + c = 0, the two roots can be found analytically by quadratic formula, whose expression is described below:

$x = \frac{-b \pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}$    

If we know that a = 2, b = - 7 and c = 1, then the roots of the polynomial are:

x = 7/4 ± (1/4) · √41

x = (7 ± √41) / 4

By using the quadratic formula, the roots of the quadratic equation 2 · x² - 7 · x + 1 are represented by the irrational number x = (7 ± √41) / 4.
