(2x-1)(2x-1) = 4x^2 -4x + 1
x^2 + 4x + 5 cannot be factored because its discriminant is less than zero.
The GCF is 4x.
It is 9*(4x + 1).
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20
Combine like terms, meaning add 12X plus 4X which is 16X and then you add 25Y plus 15Y which equals 40Y so the answer will be 16x+40y. combine like terms means add the ones with the same variable.
4x + 3 doesn't factor. It is in its simplest form.
.225
4x(10x + 1)
It is: 4x(1+4)
(4x + 3)(4x + 3) (4x + 3)2
4x + 16 + 1 = 4x + 17 which cannot be factorised.
4x(4x^2 + 3x + 1)
(4x + 5)(4x + 5)
No
4(x^2 + x + 3)
