Answer 1

Answer:

11

Step-by-step explanation:

I assume we have to open parentheses using distributive property.

1). 4a^5 + 2a³ +20a² +10

2). 21p² - 65pq + 24q²

3) - u^5 - 2u³t + + 3t²u

4). -88x² + 14x + 2

5). 144g² - 49

6). 54n² - 6m²

7). 36b²c² - 18b² - 12c² + 6

8). - 10k^6 - 60k^5 - 90k^4

Answer 2

Given :  (-a³ - 5) (-4a² - 2)   , (7p - 3q)(3p - 8q)

To find : Simplify

Solution :

(-a³ - 5) (-4a² - 2)

= -(a³ + 5)(-)(4a² + 2)

= (a³ + 5) (4a² + 2)

= 4a⁵ +2a³ + 20a² + 10

(7p - 3q)(3p - 8q)

= 7p(3p - 8q) - 3q(3p - 8q)

= 21p² - 56pq -9pq + 24q²

= 21p² - 65pq + 24q²

(12g - 7)(12g + 7)

= 144g²  - 49

(-8x + 2)(11x + 1)

= -88x² + 14x  + 2

(tu + u³)((-u² + 3t)

= - u⁵ + 3tu³ - tu³ + 3t²u

=  - u⁵ + 2tu³ + 3t²u

and similarly
