Question

What are the exact solutions of x2 - 5x - 1 = 0?

Answer 1

first you attempt to factor

if that doesnt work
use the quadratic equation

Answer 2

platinum is the x squared?

Answer 3

Use quadratic formula: a = 1, b = -5, c = -1
x = [-b±√(b²-4ac)]/(2a)
x = {-(-5)±√[(-5)²-4(1)(-1)]}/[2(1)]
x = {5±√[(25)+(4)]}/2
x = [5±√(29)]/2

Solutions: x = [5±√(29)]/2
