Question

solve $2x^2 + x - 4 = 0$.
$x^2 + \square x + \square = 0$

Explanation:

Step1: Divide all terms by 2

Divide each term in $2x^2 + x - 4 = 0$ by 2 to make the coefficient of $x^2$ equal to 1.
$\frac{2x^2}{2} + \frac{x}{2} - \frac{4}{2} = \frac{0}{2}$

Step2: Simplify each term

Simplify the resulting expression to get the required form.
$x^2 + \frac{1}{2}x - 2 = 0$

Answer:

The blanks are $\frac{1}{2}$ and $-2$, so the equation is $x^2 + \frac{1}{2}x + (-2) = 0$
