Question statement

To solve a quadratic equation $ax^2+bx+c=0$ use the formula

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a},\space \text{where}\space b^2-4ac\geq0\text{.}$

Give any introductory information the student needs.

Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Solve the following equation: $\simplify{x^2 +{r1+r2}x+{r1*r2}}=0\text{.}$

To do so, you need to find the roots $x_1$ and $x_2$ , where $x_1<x_2$

$x_1=$ Gap 0. (NB: $x_1<x_2$ )

$x_2=$ Gap 1.

Advice

Give a worked solution to the whole question.
