Question

REPONDEM PFVRRR!!

A) (2$p^{5}$ - 3$r^{3}$) $^{2}$


B) (b - 3$x^{2}$) $^{2}$

C) (b + c) (b - c)

D) 7a - 2b) (7a + 2b)

Answer 1

Explicação passo-a-passo:

a) (2p^5 - 3r³)² = 4p^10 - 12p^5r³ + 9r^6

b) (b - 3x²)² = b² - 6bx² + 9x⁴

c) (b + c)(b - c) = b² - c²

d) (7a - 2b)(7a + 2b) = 49a² - 4b²
