Solve (2x - 3y + 4z)2 using expansions identities

Answer»

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}}$

${\bf{\green{(2x-3y+4z)^2}}}$

${\bf{\green{4x^2+9y^2+16z^2-12xy-24yz+16xz)}}}$

${\bf{\green{4x^2+9y^2+16z^2+4(-3xy-6yz+4xz)}}}$

${\bf{\green{4x^2+9y^2+16z^2-4(3xy+6yz-4xz)}}}$
