Answer 1

$Question:-\\\\Simpify:\\\\(x^{2} -2y^2)^2 + 4x^{2} y^2$

Answer:-

$(x^{2} -2y^2)^2 +4x^{2} y^{2} \\\\(x^{2} -2y^2)(x^{2} -2y^2)+4x^{2} y^2\\\\(x^{2} -2y^2)x^{2} -2(x^{2} -2y^2)y^2+4x^{2} y^2\\\\x^4-2x^{2} y^2-2(x^{2} y^2)y^2+4x^{2} y^2\\\\x^{4} -2x^{2} y^2-2x^2y^2+4y^4+4x^{2} y^2\\\\x^4-4x^2y^2+4y^2-4x^2y^2\\\\x^4+4y^2$
