Question

A) (3-5x)² =

B) (2a+3b).(2a-3b) =

C) (m-4).(m-6) =​

Answer 1

Respuesta:

a + b + 2b − 2c + 3a + 2c − 3b − a + 3a = 2a b + 2b − 3b = 0 = 2a. 5 − 11= − 6 ... a = 3 b = 4 c = 1/3 d = 1/2 m = 6 n = 1/4 1. a 2 − 2ab + b 2 = 32 − 2 ⋅ 3 ⋅ 4 + 42 = 9 − 24 + 16 = 1 ... 5x 2 − x 2 + 9xy − 6xy + 7y 2 = 4x2 + 3xy + 7y2. 1.
