Answer:

Step-by-step explanation:

You haven't provided the powerpoint screens.

If ax² + bx + c = 0, then the discriminant = b² - 4ac

:::::

-6x² + 7x + 25 is not an equation; it is an expression.

a = -6, b = 7, c = 25

:::::

x² + 2x + 1  is not an equation. No equals sign.

a = 1, b = 2, c = 1

roots: x = [-2±[tex]\sqrt{2^{2}-4*1*1}[/tex]]/[2*1] = -1
