" ii) "(2x+3y+z)^(7)

Find the number of terms in the expansion of (2x+3y+z)^(7)

Find the number of terms in the expansion of (2x+3y+z)^(7)

Find the number of terms in the expansion of (2x+3y+z)^(7)

Numbers of terms in expansion (2x+3y+4z)^(7) are 8 .

Solve by matrix method 3x - 4y + 2z = -1 , 2x + 3y +5z = 7 , x+ z =2

Solve by matrix method (3x-4y+2z=-1) (2x+3y+5z=7) (x+z=2)

Put the last two terms of each of the following expressions in the parentheses preceded by a minus sign: (i) 2x+3y-4z+7 (ii) 3a-2b-7c-4d (iii) 7x y-4y z+3z x-5

If (2x)/3=(4y)/5=(7z)/9 then find the value of (4x+12y-21z)/(3y) .
