x^(2)- x + 2
(x -2)( x + 1)
NB This does NOT factor becasue '-2' X (+)1 = -2 ( as the middle term.
Since the middle term is '-1x' , then '-1' Not equal to '-2'.
However, x^(2) - x -2 does factor to
( x - 2)(x + 1)
(3r - 2)(3r - 2) or (3r - 2) squared.
9x^(2) + 16 DOES NOT factor. Remember ; two squared terms with a plus(+) between them DOES NOT factor However, two squared terms with a minus(-) between them DOES factor . Hence 9x^(2) + 16 = (3x)^2) + 4^(2) does NOT factor However, 9x^(2) - 16 = (3x)^2) - 4^(2) does factor to ( (3x - 4)(3x + 4) Note the two different signs.
it is (x-y)(x-y) :)
2(5x - 1)(3x - 2)
(2y - 5)(y - 2)
(a - 2)(a^2 + 6)
(3r - 2)(3r - 2) or (3r - 2) squared.
Factor out -2: -2(x squared +11x-20). This is fully factored.
it is (x-y)(x-y) :)
2(5x - 1)(3x - 2)
(x squared plus the square root of 2) times (x squared minus the square root of 2).
(2x - 3)(x + 2)
(x-1)(x+2)
(2y - 5)(y - 2)
(y - 2)(y - 7)
(5x - 2)(x - 5)
(x - 2)(2x + 7)
