Question

4. Desarrolle:
8.r + 5y^2 - 9.r - 5 - 3y ^2+ 4r +4y^2 + 7​

Answer 1

Respuesta:

$8. \sqrt{ \frac{ \sqrt[ {x - 2.8241x)y}^{2} ]{?} \times \frac{?}{?} }{?} }$

Answer 2

8.r + 5y^2 - 9.r - 5 - 3y ^2+ 4r +4y^2 + 7​  | multiplica -3*y^2 [multiplica x] y [y] 4*y^2

=8*r+5*y^2+-9*r+4*r+1*y^2+​*7+-5  | multiplica -9*r [multiplica x] y [y] 4*r

= 8*r+5*y^2+-5+4*r+1*y^2+1*​*7+-5  | multiplica 5*y^2 [multiplica x] y [y] 1*y^2

= 8*r+-5*r+6+1*y^2+1*​*7+-5  | multiplica 8*r [multiplica x] y [y] -5*r

= 3+-5*r+6*y^2+1*​*7+-5

espero que te ayude
