The expression ( n^2 - 3n - 4 ) can be factored by finding two numbers that multiply to (-4) (the constant term) and add to (-3) (the coefficient of the linear term). These numbers are (-4) and (1). Thus, the factored form is ( (n - 4)(n + 1) ).
3n2-8n+4 = (3n-2)(n-2) when factored
(4+x) (2x-3)
2x2-9x+4 = (2x-1)(x-4) when factored
x2-4x-165 = (x-15)(x+11) when factored
It is: (3x+4)(2x-3) when factored
3n2-8n+4 = (3n-2)(n-2) when factored
(4+x) (2x-3)
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
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.
2x2-9x+4 = (2x-1)(x-4) when factored
3x2 -14x -24 can be factored as (3x + 4)(x - 6).
It is: (3x+4)(2x-3) when factored
x2-4x-165 = (x-15)(x+11) when factored
It is x^2 -x -12 is (x+3)(x-4) when factored
x2-5x-36 = (x-9)(x+4) when factored
y2-4y-32 = (y+4)(y-8) when factored
It is: (c-4)(c-8) when factored
