2x2 - 2 =
can anybody help me?
WHAT do yo need? Do you have values for 'x' ? Do you need to find 'zeroes' ? Do you need to factor these expressions?
Yeah i need factor those expressions
2x^2 - 2 = 2 (x^2 -1) = 2(x+1) (x - 1)
x^3 - 3x^2 + 3x + 2
We can write this as
x^3 - 2x^2 + x^2 + 3x + 2 =
x^2 ( x -2) + (x + 2) (x + 1)
Notice that no factor is common....so......this polynomial is irreducible
