What else can I help you with?
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
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).
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 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}
