2x^2+4x factored

Question

How do I get the answer to factorizing

 

Answer 1

Hi Melody,

 

2x² + 4x=0

 

2x(x+2)=0

 

since the product of the two factors is zero

 

set either factor to zero and solve

 

2x = 0

x =0

 

and

 

x+2=0

x = -2

 

so the solutions are x=0 and x=-2

 

Hope this helps
