x3 + 13x2 + 42x = x(x + 6)(x + 7).
no. it can be simplified into 13x2. 13 and 2 are prime.
13x1=13 13x2=26...etc
x3 + 13x2 + 42x = x(x2 + 13x + 42) = x(x2 + 6x + 7x + 42) = x[x(x + 6) + 7(x + 6)] = x(x + 7)(x + 6)
5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)
-x2(5x5 + 13)
13x2=26 By Someone?
13x2
26. 13x2=26.
x3 + 13x2 + 42x = x(x + 6)(x + 7).
13x2 2x13
13X2
36x1 13x2 12x3 9x4 6x6
no. it can be simplified into 13x2. 13 and 2 are prime.
13x1=13 13x2=26...etc
x3+13x2=-22xadd 22x to both sides:x3+13x2+22x=0now factor:x(x2+13x+22)=0x(x+11)(x+2)=0x=0x+11=0x+2=0Therefore the solution to this equation is x=0, x=-11, x=-2
the answer is 13x2=26 posted by a genius
