Question

la simplificacion de

-(-a)[2-3]

-(-b)/-bc

4(3+c)/4c

[(4)(1/2)(-1/2)](-2)+2

(14)(0)(x)/√2-√3

(π-π)(x+y-3)

Answer 1

-(-a)[2-3] = a(2-3) = 2a-3a = -a

-(-b)/-bc = b/-bc = 1/-c

4(3+c)/4c = (12+4c)/4c = (12/4c)+1

[(4)(1/2)(-1/2)](-2)+2 = (-1)(-2)+2 = 2+2 = 4

(14)(0)(x)/√2-√3 = 0

(π-π)(x+y-3) = 0
