factor 125+b^3

factor

125 + b^{3}

(b + 5) (b^{2} - 5 b + 25)

Solution steps

125 + b^{3}

Write in the standard form

= b^{3} + 125

Rewrite

125

5^{3}

= b^{3} + 5^{3}

Apply Sum of Cubes Formula:

x^{3} + y^{3} = (x + y) (x^{2} - x y + y^{2})

b^{3} + 5^{3} = (b + 5) (b^{2} - 5 b + 5^{2})

= (b + 5) (b^{2} - 5 b + 5^{2})

5^{2} = 25

= (b + 5) (b^{2} - 5 b + 25)

10. 2^{2}

\frac{a - x}{a x ( x - a )}

1 - 4 a - 5

(d + 5)^{2}

(5 - 1) (5 + 1)
