Given:
x4 + 3x3 - 10x2 = 0
You can start by dividing both sides of the equation by x2:
x2 + 3x - 10 = 0
Then factor out the left side of the equation into simpler terms:
(x + 5)(x - 2) = 0
For the result to be 0, either of the terms in brackets on the left must equal 0, so that means there are two answers:
x = -5, x = 2

10x2 +4x + 21 = 0=> 4*x +10*x^2 +21 = 0Complex roots:Root 1: -0.2-1.435 * iRoot 2: -0.2+1.435 * i

The value of x would be 0
Yes because if 1+0=1 than 0 plus b equals b
x4-8 = 0 x4 = 8 Eradicate the the power of 4 x = 1.681792831 Check: 1.6817928314 = 8.000000009 which is just about correct.
A=0 b=0 c=0
No.
x = y = 0 ?
