Quadratic Equations Discriminant Nature of Roots Sum Product Roots
$2x^2 + 3x + 1 = 0$
$x^2 - 49 = 0$
$x^2 - x + 3 = 0$
2. The equation $2x^2 - 5x - 7 = 0$ has the roots as shown below.
$2x^2 - 5x - 7 = 0$
$(2x + 2)(x - 7) = 0$
$\frac{2(x + 1)}{2} = 0; x - 7 = 0$
$x + 1 = 0; x - 7 = 0$
$x = -1; x = 7$
a. Do you think the roots are correct? Why?
b. If you are task to find the roots of the equation, what would it be? Justify your answer with a
