sqrt(4)=2 sqrt(169)=13 (2x+13)(2x-13)
Yes, if there is no remainder after division, the divisor is a factor.
you can factorise 5x2-24x-12 if you use the quadratic formula: This goes to (24(+/-)sqrt(816))/(10) =5.257 or -0.4566 (4s.f.)
(x + 3)(4x + 5)
x2-3x+2.25 is the same as 4x2-12x+9 and is (2x-3)(2x-3) when factored
It is: 2x(2x+11)
(2x - 9)(2x - 9)
If that's + 4x2, the answer is 2x(x2 + 2x - 4)
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.
It is: 4x2-7x-15 when factored is (4x+5)(x-3)
(2x + 5)(2x - 5)
(4x+5)(x-3)
