Assume this quadratic equation equals zero. Then :-
x2 - 13x + 40 = 0, this can be factored (x - 8)(x - 5) = 0
This holds true when either x - 8 = 0 or x - 5 = 0
When x - 8 = 0 then x = 8 : When x - 5 = 0 then x = 5

Is the equation x2 plus 2x plus 1 quadratic?
It is a quadratic expression and when factored is: (x+1)(x+1)
Is 2x2 plus 7 equals 79 linear or quadratic?
It is a quadratic equation that has 2 solutions
Is -2x squared plus 2x plus 1 equals 9 a quadratic equation?
Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
X plus 5 squared plus x - 2 squared 37 solve using the quadratic formula?
You can't because it is not a quadratic equation.

How do you factor x2 plus 8x2 plus 5x plus 40?
Once you simplify it, it will become 9x2+5x+40. And, that should make it a little easier. I'm afraid I'm no help after that... hope it helps! :)Further Information:-This quadratic espression can't be factored because its discriminant is less than zero.
What is 40 plus 40 plus 40 plus 40 plus 40 plus 40 plus 40 plus 40 plus 70 plus 74 plus 85 plus 45 plus 27 plus 56 plus 84 plus 57?
this equals 818
Is 3x4 plus 2x plus 5 equals 0 a quadratic equation?
No. It is a quartic equation. The largest power of x in a quadratic equation must be 2.
What is the answer by using the quadratic formula 2a -46a plus 252 0?
