If (x + 3)(x +7) = 0 then either:
x + 3 = 0 or
x + 7 = 7
Hence x = -3 or -7.
The discriminant is 0.
It's just a mathematical polynomial: 7x + 3y.
(x + 7)(x - 5)
1
144
-2 and -6
-6 Check: -6+4-6+8 = 0
The actual equation itself is the polynomial. There is no polynomial for it, and your question doesn't really make sense.
-2.5 + 1.6583123951777i-2.5 - 1.6583123951777i
4(3j3 + 7)
12x2 + 20x - 25 IS a polynomial that factors into (2x + 5)(6x - 5)
(x+7) and (x-3)
(x+8)(x-3)
There are none because the discriminant of the given quadratic expression is less than zero.
It is (x+9(x-2) when factored
No. It factors to (11x - 13)(2x - 3)
A fifth degree polynomial.
