You can't really factor this polynomial neatly because it has one real root (between 2 and 3) and three imaginary roots.
(x + 3)(4x + 5)
(4x + 16)(x + 3)
sqrt(4)=2 sqrt(169)=13 (2x+13)(2x-13)
Yes, if there is no remainder after division, the divisor is a factor.
It is: 2x(2x+11)
If that's + 4x2, the answer is 2x(x2 + 2x - 4)
(2x - 9)(2x - 9)
4X2+X3+3X+7Y+2X3 can only be simplified to 3X3+4X2+3X+7Y, because X3 and 2X3 are the only like terms.
zero
The discriminant is 0.
(4x + 5)(x - 3)
64
Fifth degree - the highest power of x that appears.
You can't really factor this polynomial neatly because it has one real root (between 2 and 3) and three imaginary roots.
It is: 4x2-7x-15 when factored is (4x+5)(x-3)
4x2-81
