expand (5a+2x)(a+x)(a-x)

expand

(5 a + 2 x) (a + x) (a - x)

5 a^{3} - 5 a x^{2} + 2 x a^{2} - 2 x^{3}

Solution steps

(5 a + 2 x) (a + x) (a - x)

Apply Difference of Two Squares

(a + x) (a - x) : a^{2} - x^{2}

= (5 a + 2 x) (a^{2} - x^{2})

Apply FOIL method

(5 a + 2 x) (a^{2} - x^{2}) : 5 a^{3} - 5 a x^{2} + 2 x a^{2} - 2 x^{3}

= 5 a^{3} - 5 a x^{2} + 2 x a^{2} - 2 x^{3}

(49)^{- \frac{1}{2}}

\frac{3}{1 + 3}
