Question

use quadratic formula to solve:

-2x² - 5x + 3=0

Expert Solution

Step 1

Quadratic formula is used to solve any quadratic equation, i.e. an equation that can be written in the form of $a x^{2} + b x + c = 0$ , where $a \neq 0$

If the quadratic equation is of the form $a x^{2} + b x + c = 0$ , then its roots can be calculated as:

$x = \frac{- b \pm \sqrt{b^{2} - 4 a c}}{2 a}$ -(1)
