1. discriminant = b^2 - 4ac = (-5)^2 - (4 x 1 x 7) = 25 - 28 = -3 [imaginary root]
2. discriminant = (-5)^2 - (4 x 1 x -4) = 25 - (-16) = 25 + 16 = 41 [real and irrational root]
3. discriminant = (8)^2 - (4 x 16 x 1) = 64 - 64 = 0 [double root]

Answer:
start with a line segment to divide into equal parts
Step-by-step explanation:
that's the first step you take before you make the angle bisector because there's no point in doing the other steps before that
simplify each term
apply the distributive property
-X+3+(-X- -5)
multiple -1 by -5
-X+3+(-x+5)
remove unnecessary parentheses
-x+3-×+5
subtract x from -x
-2x+3+5
add 3 and 5.
-2x+8
