Sos giúp mình với,cảm ơn mn

Answer 1

\(a,=x^2+10x+25\\ b,=\dfrac{25}{4}-\dfrac{10}{2}x+x^2\\ c,=4x^2+12xy+9y^2\\ d,=\dfrac{4}{9}y^2-2.\dfrac{1}{8}x.\dfrac{2}{3}y+\dfrac{1}{64}x^2\\ e,\left(\dfrac{x^2}{16}-\dfrac{y^2}{36}\right)\\ f,=4x^2-4xy+y^2\\ g,=\dfrac{16}{9}x^2-2.\dfrac{4}{3}x.\dfrac{1}{2}y+\dfrac{1}{4}y^2\\ h,=\dfrac{9}{16}x^4-2.\dfrac{3}{4}x^2.1+1\)

Answer 2

a: \(=x^2+10x+25\)

b: \(=\dfrac{25}{4}-5x+x^2\)

c: \(=4x^2+12xy+9y^2\)

d: \(=\dfrac{x^2}{16}-\dfrac{y^2}{36}\)
