Resolve a equação $x^2 - 5x + 6 = 0$ usando a fórmula resolvente.
$x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}$
Resolution:
1
Medium
Qual é o valor do binómio discriminante de $2x^2 + 3x - 5 = 0$?
A) $\Delta = 49$
B) $\Delta = 9$
C) $\Delta = -31$
D) $\Delta = 29$

Easy
Resolve cada equação incompleta.
$x^2 = 49 \Rightarrow x = \pm\,\_\_\_$
$(x - 3)^2 = 0 \Rightarrow x = \_\_\_$
$x^2 - 9 = 0 \Rightarrow x = \pm\,\_\_\_$

Hard
Indica se cada afirmação é verdadeira ou falsa.
1.
$x^2 = 16$ tem as soluções $x = 4$ e $x = -4$.
2.
$x^2 + 1 = 0$ tem soluções reais.
3.
$(x + 2)^2 = x^2 + 4x + 4$.
5
Hard
Liga cada equação ao seu conjunto-solução.

$x^2 - 4 = 0$
$x^2 - 5x + 6 = 0$
$x^2 - x - 6 = 0$
The worksheet was produced on the platform. Any student, class or mark shown in other examples on this site is invented — Matilde S. and her numbers were made up to show the format.
The worksheet is the extra. The record is the product.
Generating materials is useful and there are good tools doing it. What none of them keeps is what happened with each student across the year — and that is what sits at the centre of LearnxBoost.
