Question 17
The expression obtained when x is multiplied by 2 and then subtracted from 3 is
(a) 2x−3
(b) 2x+3
(c) 3−2x
(d) 3x−2
Option (c).
x is multiplled by 2 can be expressed as 2×x=2x.
2x is subtracted from 3 can be expressed as 3−2x.
The expression obtained by multiplying (7x−4x2+2x3−5) with (3x−2) is:
