Question

Solve 5x2 = −30x − 65

Answer 1

I hope this helps you




5x^2+30x+65=0




5 (x^2+6x+13)=0



x^2+6x+13=0



a=1 b=6 c=13



disctirminant=b^-4ac



disctirminant=6^2-4.1.13



disctirminant=36-52



disctirminant= -16


x1= -6+square root of -16/2.1



x1= -6+4i/2=2i-3



x2= -6- square root of -16/2.1



x2= -6-4i/2= -3-2i
