Answer 1

Respuesta:

(10x + 5x - 3x - 11) + (8 + 3x - x + 2x) =

(12x - 11) + (8 + 4x) =

96x + 48x² - 88 - 44x =

48x² + 52 x - 88

(ax + 7xy + 9z) + (78ax + 19xy - 38z) =

ax + 7xy + 9z + 78ax + 19xy - 38z =

79ax + 26xy - 29z

(4a + b² - 1) - (a² - 3b²) =

4a + b² - 1 - a² + 3b² =

-a² + 4a - 4b² - 1

(19ax + 17xd - 20z) - (30z + 18xd - 75 ax)=

19ax + 17xd - 20z - 30z - 18xd + 75ax=

94ax - 1xd - 10z

(-3xy + 4yz - 2xz) x (13xy + 24yz - 12xz) =

-39x²y² - 72xy²z + 36x²yz + 52 xy²z + 96y²z² - 48xyz² - 26x²zy - 48xyz² + 24x²z² =

153x²y² - 20xy²z - 10x²yz - 96xyz² =

xy (153xy - 20yz - 10xz - 96z²)

espero te ayude(:
