Use the FOIL method.
F: First
O: Outter
I: Inner
L: Last
(x)(x) = x^2
(x)(5) = 5x
(3)(x) = 3x
(3)(5) = 15
x^2 + 5x + 3x + 15
-> Now combine any like numbers
5x + 3x = 8x
x^2 + 8x + 15
Now we evaluate:
x^2 + 8x + 15 = 0
What numbers make the expression equal to zero?
-3^2 +8(3) + 15 = 0
0 = 0
-5^2 + 8(-5) + 15 = 0
0 = 0
Final answer
x = -3, -5

(x+3)(x+5)
=x^2 + (3+5)x + 3*5 [by using (a+b)(a+c) = a^2 + (b+c)a + bc]
=x^2 + 8x + 15

the actual area of (-4+4i?3) is Cos(?/9) + ?3 Sin(?/9) which has the complicated expression of ((a million/2)(-a million+i?3))^(-a million/3) + ((a million/2)(-a million+i?3))^(a million/3) that's certainly a root of the equation x³ -3x + a million. enable me see if i'll discover yet differently of proving this. Oh, ksoileau has already beaten me to this. Kudos, ksoileau, good paintings. I also see that (?) Dr D has fastened his answer too. Thumbs up for both.

If x=negative 3 or negative 5, then the expression has a zero value.
