(x2 + 3x + 5)(x2 - 3x + 4)
x squared minus 12 x plus 36 = (x - 6)(x - 6)
I'm not sure this was notated correctly. As written, this is -11x plus or minus 18, which doesn't factor.
(x + 12)(x - 3)
7(3x plus or minus 5) depending on the missing sign.
(2x - 3)(x + 2)
No.
it is prime. it cannot factor out.
6a to the second power minus 8ab + 2a
(-7x + 3)(-7x +3)
(2x - 1)(x + 4)
2(2x^3 - 140x + 147)
That would depend on the plus or minus value of 2 which has not been given.
This is not factorable. You would have to do the quadratic formula for this problem.
x sq equalls 36 and x equalls plus or minus 6
Same mathematical signs equal plus Different mathematical signs equal minus Plus Plus = Plus (+)(+) = + Minus Minus = Plus (-)(-) = + Plus Minus = Minus (+)(-) = - Minus Plus = Minus (-)(+) = - So the direct answer to your question would be: plus minus equals minus
simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34
64x2-80x+25 = (8x-5)(8x-5) when factored
