I don't know Spanish I would like to help you ;(

Answer 2

Respuesta:

Buenas noches UwU xD.

Explicación paso a paso:

(7x^2+2) - (3x^2-5)

=7x2+2+−1(3x2−5)

=7x2+2+−1(3x2)+(−1)(−5)

=7x2+2+−3x2+5

=(7x2+−3x2)+(2+5)

=4x2+7

(5x^3)(9x^2)

=5x3*9x2

=5*x3*9*x2

=(5*9)*(x3*x2)

=45*x5

=45x5

(15x^3-10x^2) ÷ 5x^2

=3x5−2x4

(-2y^2)(-3y)

=(−2)*y2*(−3)*y

=6*y3

=6y

(10x-5y) ÷ 5

=2x−y

Listo cariño:3!
