Question

expend (2x-y+z)2
answer me fast​

Answer 1

Step-by-step explanation:

(2x-y+z)^2

using the formula

$(a + b + c)^{2} = ( {a}^{2} + {b}^{2} + {c}^{2} + 2ab + 2bc + 2ca)$

here a = 2x , b = -y and c = z

so (2x-y+z)^2=

(2x)^2 + (-y)^2 + (z)^2 + 2(2x)(-y) + 2(-y)(z) + 2(z)(2x) =

4x^2 + y^2 + z^2 -4xy - 2yz + 4xz
