Not being an equation, it does not have a "solution" per se.
If you wish to factor it, you can do it like so:
x2 + 20 - 9x
= x2 - 5x - 4x + 20
= x(x - 5) - 4(x - 5)
= (x - 4)(x - 5)
If that expression is equal to zero, then x would be equal to 4 or 5.

Simplify -8x3 plus 5x2 - 4x - 3 plus x2 plus 9x - 8?
i thinking this answer should be -20
What is 9x plus x2?
A binomial
What is the answer to x2-9x plus 21 equals 0?
This quadratic equation has no solutions because its discriminant is less than zero.
Factor x2 plus 9 plus 20?
x2 + 9 + 20 = x2 + 29, and can not be factored.I assume though that you mis-wrote your question, and what you in fact want to ask is how to factor x2 + 9x + 20.In that case, the answer is (x + 4)(x + 5).
Factor 9x cubed plus 27x squared -90x?
Step 1: Divide by 9x: 9x (x2 + 3x - 10) = 9x(x + 5)(x - 2)
What is x2 equals 9x-20?
x2=9x-20 x2-9x+20=0 Factor: (x-4)(x-5)=0 x={4,5}

What binomial is a factor of both x2 plus 5x-36 and x2-9x plus 20?
x - 4. x^2 + 5x - 36 = (x - 4) (x + 9) x^2 - 9x + 20 = (x - 4) (x - 5)
Lcd x2-9x plus 18?
x2-9x+18 = (x-3)(x-6) when factorised
Factor 9x cubed plus 27x squared -90x?
Step 1: Divide by 9x: 9x (x2 + 3x - 10) = 9x(x + 5)(x - 2)
What is the polynomial of this factor x2 minus 9x plus 18 in descending order?
x2 - 9x + 18 = (x - 3)(x - 6)
X squared plus nine x plus 20 equals 0?
x2 + 9x + 20 = 0 ∴(x + 4)(x + 5) = 0 ∴x ∈ {-5, -4}
How do you factor x squared plus 9 x squared plus 20 equals 0?
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
