Solution steps

One step at a time

2x²+4x−6

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

2x²+4x−6=0

Solve with the quadratic formula

x_{1, 2}=−4± √4²−4· 2(−6)2· 2

√4²−4· 2(−6)=8

x_{1, 2}=−4± 82· 2

Separate the solutions

x₁=−4+82· 2 , x₂=−4−82· 2

x=−4+82· 2 : 1

x=−4−82· 2 : −3

The solutions to the quadratic equation are:

x=1, x=−3
