PLEASSSEEEE HELLLLP MEEEE!
Vanyuwa [196]

Answer:

1) C = 3

2) B = 5

3) C = 8

Step-by-step explanation:

Question 1)

We have:

(2x+3)(4x-1)

Distribute:

=(2x+3)(4x)+(2x+3)(-1)

Distribute:

=8x^2+12x-2x-3

Combine like terms:

=8x^2+10x-(3)

Therefore, C = 3.

Question 2)

We have:

(x+2) (2x^2+x-1)

Distribute:

\displaystyle =(x+2)(2x^2)+(x+2)(x)+(x+2)( - 1)

Distribute:

=(2x^3+4x^2)+(x^2+2x)+(-x -2)

Combine like terms:

=2x^3+(5)x^2+x-2

Therefore, B = 5.

Question 3)

We have:

(x+2)(x^2-3x-2)

Distribute:

=(x+2)(x^2)+(x+2)(-3x)+(x+2)(-2)

Distribute:

=(x^3+2x^2)+(-3x^2-6x)+(-2x-4)

Combine like terms:

=x^3-x^2-(8)x-4

So, C = 8.
