expand (a+2)(a-3)(a-2)(a+3)

expand

(a + 2) (a - 3) (a - 2) (a + 3)

a^{4} - 13 a^{2} + 36

Solution steps

(a + 2) (a - 3) (a - 2) (a + 3)

Expand

(a + 2) (a - 3) (a - 2) (a + 3) : (a^{2} - 4) (a - 3) (a + 3)

= (a^{2} - 4) (a - 3) (a + 3)

Apply Difference of Two Squares

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

= (a^{2} - 4) (a^{2} - 9)

Apply FOIL method

(a^{2} - 4) (a^{2} - 9) : a^{4} - 13 a^{2} + 36

= a^{4} - 13 a^{2} + 36

7^{3 l o g_{7} (2) + 2 l o g_{7} (3)}

(6)^{4}

lo g_{e} (7)

\frac{- 20 ( m ^{2} v ) ( - v ) ^{3}}{5 ( - v ) ^{2} ( - m ^{4} )}

s (s + 1)^{2}
