If you mean: x2+3x+2 then it is (x+1)(x+2) when factored
This quadratic expression can't be factored because its discriminant is less than zero.
-7
x2 + 3x + 7 = 5 ∴ x2 + 3x + 2 = 0 ∴ (x + 1)(x + 2) = 0 ∴ x ∈ {-2, -1}
3x-1 = 11 3x = 11+1 3x = 12 x = 4 Therefore: x2+2 = 18
If you mean: x2+3x+2 then it is (x+1)(x+2) when factored

"(x - 5)(x - 2)"
x2 + 3x + 28 can not be factored. If on the other hand you meant to type: x2 + 3x - 28 That can indeed be factored: = x2 + 7x - 4x - 28 = x(x + 7) - 4(x + 7) = (x - 4)(x + 7)
If you mean: x2+3x+2 then it is (x+1)(x+2) when factored
x2-3x-10 = (x+2)(x-5) when factored
x2+3x-10 = (x+5)(x-2) when factored
48
x2+3x-5 = (x+4.192582404)(x-1.192582404) factored with the help of the quadratic equation formula
x2 - 3x + 2 = 0
This quadratic expression can't be factored because its discriminant is less than zero.
If you mean: x^2 +3x -10 then when factored it is (x-2)(x+5)
