It has one double solution.

Divide all terms by 3 and so x2+18x+81= (x+9)(x+9) when factored

(x+3)(x+15)

(2x4) + (8x3) + 18x 8 + 24 + 18x 32 + 18x

x2 + 18x + 45 = (x + 15)(x + 3).

-3x2 + 16x + 12 = -3x2 + 18x - 2x + 12 = -3x*(x - 6) - 2(x - 6) = -(3x + 2)*(x - 6)

It has one double solution.

6x(3x2 - x + 4)

Divide all terms by 3 and so x2+18x+81= (x+9)(x+9) when factored

(x+3)(x+15)

(2x4) + (8x3) + 18x 8 + 24 + 18x 32 + 18x

-3(x + 3)(x + 3)

no 3x2=6 then 4x-15= -60 so 6 added with - 60 = -54

x2 + 18x + 45 = (x + 15)(x + 3).

9x2 - 18x = -3x2 - 2x = -1/3x2 - 2x + 1 = 1 - 1/3(x - 1)2 = 2/3x - 1 = ±√2/3x = 1 ± (1/3)√6)
