You can put this solution on YOUR website! Solve equation by factoring
9x^2+5x-11=0
(3x)^2 + 2.3x.5/6 + (5/6)^2 - 11 - (5/6)^2 = 0
[3x + 5/6]^2 - [11 + 25/36] = 0
[3x + 5/6]^2 - [421/36] = 0
[3x + 5/6]^2 - [sqrt(421)/6]^2 = 0
[3x + 5/6 + sqrt(421)/6][3x + 5/6 - sqrt(421)/6]= 0
Equate each factor to 0 and that will give you two solutions.
