Question

Subtract 4y(2x+y+z) from 3x(x+y-z)........................plz dont spam

Answer 1

$4y(2x + y + z) - 3x(x + y + z)$

$(8xy + 4 {y}^{2} + 4yz) - (3 {x}^{2} + 3xy - 3xz)$

$(8xy + 3xy) + (4 {y}^{2} + 3 {x}^{2} ) - (4yz - 3xz)$

$(11 {x}^{2} {y}^{2} ) + (7 {x}^{2} {y}^{2} ) - (1xy)$

$(18 {x}^{4} {y}^{4} ) - (1xy)$

$(18 {x}^{4} {y}^{4} - 1xy)$

$17 {x}^{3} {y}^{3}$
