Answer:
x= -1+- i√35/2(looks weird so I'll include an image)
Step-by-step explanation:
depends on what you wanted to do with this equation, but I'm going to assume you wanted to factor this.
(-b+- √b^2-4ac)/(2a)=
-1+- √1- 4(1)(9)/ 2=
-1+- √1- 36/ 2=
x= -1+- i√35/2
Answer:
2x+11
Step-by-step explanation:
because x+x=2x
