expand (5a+3b+2c)(5a-3b-2c)

expand

(5 a + 3 b + 2 c) (5 a - 3 b - 2 c)

25 a^{2} - 9 b^{2} - 12 b c - 4 c^{2}

Solution steps

(5 a + 3 b + 2 c) (5 a - 3 b - 2 c)

Distribute parentheses

= 5 a \cdot 5 a + 5 a (- 3 b) + 5 a (- 2 c) + 3 b \cdot 5 a + 3 b (- 3 b) + 3 b (- 2 c) + 2 c \cdot 5 a + 2 c (- 3 b) + 2 c (- 2 c)

Simplify

5 a \cdot 5 a + 5 a (- 3 b) + 5 a (- 2 c) + 3 b \cdot 5 a + 3 b (- 3 b) + 3 b (- 2 c) + 2 c \cdot 5 a + 2 c (- 3 b) + 2 c (- 2 c) : 25 a^{2} - 9 b^{2} - 12 b c - 4 c^{2}

= 25 a^{2} - 9 b^{2} - 12 b c - 4 c^{2}

p^{2} + p

(3 a + 7 b)^{3}

(5 p^{2})^{2} \cdot (2 p^{3})^{3}

2 x - y - 8.2 y - 3 y - 6

(((x^{2})^{x})^{3})^{x}
