6x^2+13x-5=0
6x^2+15x-2x-5=0
3x(2x+5)-1(2x+5)=0
2x+5=0 , 3x-1=0
x=-5/2 , x=1/3

Answer 14

you guys are right!

Answer 15

Yeah I did as well. Thats what I had chose above. Since you got the same answer as I did that means B is the solution. Can you help with the 1st, 3rd, and 4th one now?

x^3+64=0
(x+4)(x^2-4x+16)=0
real solution =-4
