Question

Zadanie Zamień sumę algebraiczną na iloczyn.

a) 4x(3-y)+1/2(3-y)

b) (2x-1)+11(2x-1)

c) -6(1/2x+y)-(-20)(1/2x+y)

d) -3/4x(y+5)-(y+5)

Answer 1

a) 4x(3-y)+½(3-y)=(3-y)(4x+½)

 

b) (2x-1)+11(2x-1)=(2x-1)(1+11)=(2x-1)*12

 

c) -6(½x+y)-(-20)(½x+y)=(½x+y)(-6+20)=(½x+y)*14

 

d) -¾x(y+5)-(y+5)=(y+5)(-¾-1)=(y+5)*(-1¾)
