factor 27-a^3

Solution

factor

27 - a^{3}

Solution

- (a - 3) (a^{2} + 3 a + 9)

Solution steps

27 - a^{3}

Write in the standard form

= - a^{3} + 27

Factor out

- 1 : - (a^{3} - 27)

= - (a^{3} - 27)

Factor

a^{3} - 27 : (a - 3) (a^{2} + 3 a + 3^{2})

= - (a - 3) (a^{2} + 3 a + 3^{2})

3^{2} = 9

= - (a - 3) (a^{2} + 3 a + 9)

Popular Examples

simplify (64x^2-49y^2)/(8x-7y)simplify

\frac{64 x ^{2} - 49 y ^{2}}{8 x - 7 y}

x=(150(1500)}{(\frac{pi18^2)/4)120}

x = \frac{150 ( 1500 )}{( \frac{π 1 8 ^{2}}{4} ) 120}

3 x^{2} = 12

1/2 20t^2= 1/2 12(t-3)^2

\frac{1}{2} 20 t^{2} = \frac{1}{2} 12 (t - 3)^{2}

4 w^{2} + 4 w + 1 = 75
