Porfavor ayúdenme ​

Answer 1

Respuesta:

a.

(x³+ 2X²) - (-3x³-5X²)

$x^3 + 2x^2 + 3x^3 + 5x^2\\\\4x^3 + 7x^2$

b.

(2X² + 5X) - ( 5X²+3X)

$2x^2 + 5x - 5x^2 - 3x\\\\-3x^2 + 2x$

c.

(3x²y³- 7x³y²)-(-9x²y² - 10x³y²)

$3x^2y^3 - 7x^3y^2+9x^2y^2+10x^3y^2\\\\12x^2y^3+3x^3y^2$

d.

(12a⁵b⁶ + 4a²b³)-(-12a⁵b⁶ - a⁴b³)

$12a^5b^6+4a^2b^3+12a^5b^6+a^4b^3\\\\24a^5b^6+5a^2b^3$

e.

(-2c³d⁵ - 40c⁴d⁶ )-(-8c⁴d⁶ + 6c³d⁵)

$-2c^3d^5-40c^4d^6+8c^4d^6-6c^3d^5\\\\-8c^3d^5 -32c^4d^6$
