What is the simplest form of this expression? (x 7)(3x − 8) a. 3x2 2x − 15 b. 3x2 29x − 1 c. 3x2 − 29x − 56 d. 3x2 13x – 56

garri49 [273]

Assuming that the equations are (x+7) and (3x-8) because the first equation does not have a sign these are the steps. When you multiply you will get 3x^2+21x-8x-56. After this you will simplify and you will get your final answer which is 3x^2+13x-56. Also if I used the wrong equations please let me know and I can help you with the correct ones.

What is the product x^2-16 over 2x+8 • x^3-2x^2+x over x^2+3x-4

Oxana [17]

Answer:

$\dfrac{x^3-5x^2 +4x}{2x+8}$

Step-by-step explanation:

The basic idea is to factor each expression and cancel common factors from numerator and denominator.

$\dfrac{x^2-16}{2x+8}\cdot\dfrac{x^3-2x^2 +x}{x^2+3x-4}=\dfrac{(x-4)(x+4)}{2(x+4)}\cdot\dfrac{x(x-1)^2}{(x+4)(x-1)}\\\\=\dfrac{(x-4)x(x-1)}{2(x+4)}\cdot\dfrac{(x+4)(x-1)}{(x+4)(x-1)}\\\\=\boxed{\dfrac{x^3-5x^2 +4x}{2x+8}}$
