Question

Doprowadź do najprostszej postaci wyrażenia:

a) (2p-3)-(3p+4)

B) (4t+6)+(-9-t)

c)8g-(5g-7)-8

d) -9m+(7-m)-(7m-9)

e)-y-(5+y-y2)+2y2*y2 to y do potęgi drugiej

f) 2x-(-3x-6x3)+(-x3-6x+1) *x3 to x do potęgi 3

Answer 1

 

a) -p-7

b) 3t-3

c)3g-1

Answer 2

a) (2p-3)-(3p+4) = 2p-3 - 3p-4 = -p-7

 

b) (4t+6)+(-9-t) = 4t+6-9-t = 3t -3

 

c) 8g-(5g-7)-8 = 8g- 5g+7-8 = 3g -1 

 

d) -9m+(7-m)-(7m-9) = -9m+7-m-7m-9 = -17m-2 

 

e)-y-(5+y-y2)+2y2*y2= -y-5-y+y2+2y4 = -2y-5+y2+2y4

 

f) 2x-(-3x-6x3)+(-x3-6x+1) *x3 = 2x+3x+6x3-x3-6x+1 *x3 = -x+6x3
