Question

Решите пожалуйста!!!!Преобразуйте выражение в многочлен.

Answer 1

$1)(3/2p^2+2/3g)^2=9/4p^4-2p^2g+4/9g^2$
$2)(2m^3n^2-5/2mn^3)^2=4m^6n^4-10m^4n^5+25/4m^2n^6$
$3)(1,2xy+0,7x^2)^2=1,44x^2y^2+1,68x^3y+0,49x^4$

Answer 2

$( \frac{2}{3} q- \frac{3}{2}p^2 )^2= \frac{4}{9} q^2+ \frac{9}{4} p^4-2qp^2$

$(2m^3n^2-2.5mn^3)^2=4m^6n^4+6.25m^2n^6-10m^4n^5$

$(1.2xy+0.7x^2)^2=1.44x^2y^2+0.49x^4+1.68x^3y$
