X^2-4x-5=0
use quadratic formula to solve

This is geometry. could anyone ? i can't fail this class. my grade is quite low already.

F(x) = (x^2 + 3x − 4) and g (x) = (x+4) find f/g and state the domain.

A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true? a. a, b, c, and d lie on the same line. b. and are perpendicular lines. c. and are parallel lines. d. and are intersecting lines but are not perpendicular. e. and are parallel lines.
