If S represents the greater of the two solutions of the equation

Question

x^2 - 4x - 3 = 5, then :

A) S>3
B) S<3
C) S=3
D) relationship cannot be determined

and why ?

I don't understand this one at all.

Answer 1

x^2 - 4x - 3 = 5
x^2 - 4x - 8 = 0

using the formula I got x = 2 +/- √12
the larger of which is clearly > 3

Answer 2

how did you figure out the formula ?

Answer 3

I was talking about the quadratic formula
for ax^2 + bx + c = 0
x = (-b ± √(b^2 - 4ac))/(2a)

remember that?

Answer 4

Oh, I see now.
sorry.
