Question

4. Calculate the following products: a. X- (2x - 3)


b. (4a + b) - 2b


C (x + 2) - (x + 2)


d. (x- 1) - (y + 2)


e. (a -b) - (a + b)


f. 4xy (-x-3+ y)​

Answer 1

Resposta:

a. x- (2x - 3)  =-x+3

b. (4a + b) - 2b =4a-b

C (x + 2) - (x + 2) = 0

d. (x- 1) - (y + 2) =x-y -3

e. (a -b) - (a + b) =-2b

f. 4xy (-x-3+ y)​ =-4x²y  -12xy +4xy²
