Answer

The solutions are \( x = -\frac{1}{2} \) and \( x = 3 \).

Solution

Solve the equation \( 2x^2=5x+3 \). Solve the quadratic equation by following steps: - step0: Solve by factoring: \(2x^{2}=5x+3\) - step1: Move the expression to the left side: \(2x^{2}-5x-3=0\) - step2: Factor the expression: \(\left(x-3\right)\left(2x+1\right)=0\) - step3: Separate into possible cases: \(\begin{align}&x-3=0\\&2x+1=0\end{align}\) - step4: Solve the equation: \(\begin{align}&x=3\\&x=-\frac{1}{2}\end{align}\) - step5: Rewrite: \(x_{1}=-\frac{1}{2},x_{2}=3\) The solutions to the equation \(2x^2 = 5x + 3\) are \(x = -\frac{1}{2}\) and \(x = 3\).

The Deep Dive

To solve the equation \( 2x^{2} = 5x + 3 \), you first need to set it to standard form by moving everything to one side. Rearranging gives \( 2x^{2} - 5x - 3 = 0 \). Now, you can apply the quadratic formula \( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \) where \( a = 2 \), \( b = -5 \), and \( c = -3 \). After inserting the values into the formula, calculate the discriminant \( b^2 - 4ac \) to determine the nature of the roots. Once that's done, plug in the values and solve for \( x \)! To double-check your solutions, substitute the values of \( x \) back into the original equation to ensure both sides are equal. This not only confirms your solutions but also strengthens your understanding of how quadratic equations work!
