(x - 1)(x - 14)
Add like terms together: 21x-21
3x2 - 15x + 42 = 3*(x2 - 5x + 14) which cannot be factorised further.
x(x + 2)
i got 42 divided 7x
x2+15x+14 = (x+1)(x+14)
You can't factor it
3x2 + 15x + 6 = 3*(x2 + 5x + 2). There are no further rational factors.
X2+Y3+15 All you can do is simplify it.
(x + 7)(x + 8)
The correct classification of x2 15x is a monomial.
(x-11)(x-4)
(x - 1)(x - 14)
Add like terms together: 21x-21
3x2 - 15x + 42 = 3*(x2 - 5x + 14) which cannot be factorised further.
x(x + 2)
This question does not make sense. If it should be X2 x 15X -54, the answer is: X2 -15X + 54 = (X - 6)(X -9)
