x²−x−6

The roots are the intercepts with the x-axis (y=0)

x²−x−6=0

Solve with the quadratic formula

x_{1, 2}=−(−1)± √(−1)²−4· 1· (−6)2· 1

√(−1)²−4· 1· (−6)=5

x_{1, 2}=−(−1)± 52· 1

Separate the solutions

x₁=−(−1)+52· 1 , x₂=−(−1)−52· 1

x=−(−1)+52· 1 : 3

x=−(−1)−52· 1 : −2

The solutions to the quadratic equation are:

x=3, x=−2
