First, rearrange the equation to standard form: $2x^2 - 5x - 7 = 0$. Using the quadratic formula, $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$, where $a = 2$, $b = -5$, and $c = -7$, we find the solutions to be $x = \frac{7}{2}$ and $x = -1$.

Solve the Equation 2x2−5x=72 x ^ { 2 } - 5 x = 72x2−5x=7

Solve the Equation $2 x ^ { 2 } - 5 x = 7$
