7 0

Answer:

2a^2 + 3a - 1 ,

Step-by-step explanation:

I am assuming you mean

2a^3-a^2-7a+2

By long division:

a - 2 ) 2a^3 -   a^2 - 7a +  2 ( 2a^2 + 3a - 1 <------- Quotient

          2a^3 - 4a^2

                     3a^2 - 7a

                     3a^2 - 6a

                                -a + 2

                                -a + 2

                                 . . . . .

11b-7-3n+8-5b+9n what is the answer
Sergio [31]

Answer:

6 n + 6 b + 1

Step-by-step explanation:

Simplify the following:

11 b - 7 - 3 n + 8 - 5 b + 9 n

Grouping like terms, 11 b - 7 - 3 n + 8 - 5 b + 9 n = (9 n - 3 n) + (11 b - 5 b) + (8 - 7):

(9 n - 3 n) + (11 b - 5 b) + (8 - 7)

9 n - 3 n = 6 n:

6 n + (11 b - 5 b) + (8 - 7)

11 b - 5 b = 6 b:

6 n + 6 b + (8 - 7)

8 - 7 = 1:

Answer: 6 n + 6 b + 1

hjlf

Answer:

2x² + 9x - 5

Step-by-step explanation:

Given

(2x - 1)(x + 5)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(x + 5) - 1(x + 5) ← distribute both parenthesis

= 2x² + 10x - x - 5 ← collect like terms

= 2x² + 9x - 5
