Question

Quadratic equation x2+x+9=0

Answer 1

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 2

Answer:

2x+11

Step-by-step explanation:

because x+x=2x

2+9=11

Equation: 2x+11
