Expand of the expression : `(2x-3)^6`

Text Solution

Verified by Experts

The correct Answer is:
N/a
`(2x-3)^(6)=^(6)C_(0)(2x)^(6)(-3)^(0)+^(6)C_(1)(2x)^(5)(-3)^(1)`
`+^(6)C_(2)(2x)^(4)(-3)^(2)+^(6)C_(3)(2x)^(3)(-3)^(3)`
`+^(6)C_(4)(2x)^(2)(-3)^(4)+^(6)C_(5)(2x)^(1)(-3)^(5)`
`+^(6)C_(6)(2x)^(0)(-3)^(6)`
`=(1xx64x^(6))+{6xx32x^(5)xx-3}+{15xx16x^(4)xx9}`
`+{20xx8x^(3)xx(27)}+{15xx4x^(2)xx81}`
`+{6xx2x xx(-243)}+{1xx729}`
`=64x^(6)-576x^(5)+2160x^(4)-4320x^(3)+4860x^(2)`
`-2916x+729`
