Question 299596
{{{2x^2+6x-56=0}}} Start with the given equation



{{{2(x+7)(x-4)=0}}} <a href=http://www.algebra.com/algebra/homework/playground/change-this-name4450.solver>Factor</a> the left side.




Now set each factor equal to zero:

{{{x+7=0}}} or  {{{x-4=0}}} 


{{{x=-7}}} or  {{{x=4}}}    Now solve for x in each case



So the solutions are 


 {{{x=-7}}} or  {{{x=4}}}
