expand (5a^{x+1}-7)(5a^{x+1}-4)

expand

(5 a^{x + 1} - 7) (5 a^{x + 1} - 4)

25 a^{2 (x + 1)} - 55 a^{x + 1} + 28

Solution steps

(5 a^{x + 1} - 7) (5 a^{x + 1} - 4)

Apply FOIL method

(5 a^{x + 1} - 7) (5 a^{x + 1} - 4) : 25 a^{2 (x + 1)} - 55 a^{x + 1} + 28

= 25 a^{2 (x + 1)} - 55 a^{x + 1} + 28

2 (a + b) + 5 (- a + 2 b)

(2 x - 5 y)^{3} - (2 x + 5 y)^{3}

2 x \cdot 5. 5^{2}

x^{1} + x^{2} + x^{3}

(2 x + 5)^{6}
