Answer:
x = -2
If the steps aren't belong to the lesson that you want, just tell me the lesson title so I can get the answer for you !!!!

The steps
Multiply all terms by (x-3)(x+3) and cancel:
x(x+3)+2x(x−3)=18
3x2−3x=18(Simplify both sides of the equation)
3x2−3x−18=18−18(Subtract 18 from both sides)
3x2−3x−18=0
3(x+2)(x−3)=0(Factor left side of equation)
x+2=0 or x−3=0(Set factors equal to 0)
x=−2 or x=3
Check answers. (Plug them in to make sure they work.)
x=−2 (Works in original equation)
x=3 (Doesn't work in original equation)
Answer:
1001
1
Step-by-step explanation:
If a quadratic function crosses the x-axis twice, it has two solutions. For a quadratic function in 
with discriminant 
, the following is true:
- If
, then the quadratic has two real solutions - If
, then the quadratic has one real solution - If
, then the quadratic has no real solutions
Therefore, in order to have two solutions, a quadratic's discriminant must be larger than 0. The only two answer choices that satisfy this are 1001 and 1.
I don't see the answer choices, but 2 equations you could use to get eighteen would be:
9 × 2 = 18
OR
9 + 9 = 18
See? Twice a number is eighteen. You can use any of my equations to get eighteen
