Nov 3, 2016 · Because factoring x^3+27 is the same as finding where the graph passes through the x axis, we can just set the equation equal to zero and solve. f(x) = (x+3)(x^2-3x+9) Let f(x) = x³ + 27 0 = x³ + 27 x³= -27 x = -3 This means that x = -3 is the only zero of the graph of f(x). Since we know (x+3) is one factor of f(x), to find the 2nd factor, (x^3+27)/(x+3) We get the second …

Apr 18, 2018 · The greatest common factor of 27 and 36 is 9. One way to find the greatest common factor (GCF) is to list all of the factors for the numbers. Factors are all of the ...

Mar 15, 2016 · Use the difference of cubes identity to find: x^3-27 = (x-3)(x^2+3x+9) Both x^3 and 27=3^3 are perfect cubes. So we can use the difference of cubes identity: a^3-b^3 = (a-b)(a^2+ab+b^2) with a=x and b=3 as follows: x^3-27 =x^3-3^3 =(x-3)(x^2+x(3) + 3^2) =(x-3)(x^2+3x+9) This is as far as you can go with Real coefficients. If you allow Complex …

Feb 28, 2016 · x^2-6x-27=(x+3)(x-9) factors of 27 are 3 and 9 which when subtracted will result to 6. The sign of 27 is negative which tells us that we are going to subtract the factors to obtain 6. God bless....I hope the explanation is useful.

The factors are:" "1,2,3,6,9,18,27,54 Find the square root first sqrt54~~ 7.35 Half of the factors will be less than this.
