(x-5)(x^2+4x-2) PLEASE HELP

Mathematics
1 answer:
ANEK [815]3 years ago
4 0

Answer:

Simplifed (X-5)(x^2+4x-2) = x^3 − x^2 − 22x + 10

Step-by-step explanation:

Expand ( x − 5 ) ( x^2 + 4x − 2 ) by multiplying each term in the first expression by each term in the second expression.

x ⋅ x^2 + x (4x) + x ⋅ −2 −5x^2 − 5 (4x) −5 ⋅ −2

Simplify terms.

x^3 − x^2 − 22x + 10

I hope this helps.

The model shows that we are to arrange the factors based on the terms in the square box. The factored form is(6x+5)(x-4)

<h3>Factorizing quadratic equations</h3>

Factorization is a way of simplify. Given the equation 6x² - 19x - 20

Factorize

6x² - 19x - 20

6x² - 24x + 5x- 20

6x(x-4)+5(x-4)

(6x+5)(x-4)

We are to arrange each term of the factors in the square box

The current of a river is 3 miles per hour. A boat travels to a point 176 miles upstream and 176 miles back in 19 hours. What is
serious [3.7K]

Answer:

If I am understanding your question, the total upstream is 8 miles and another 8 miles downstream.

Let s = the speed of the boat in still water

d = rt

8 = 5(s + 3)  downstream

8 = 5s + 15  equation 1

8 = 5(s - 3)   upstream

8 = 5s - 15    Add equation 1

8 = 5s + 15 

16 = 10s    Divide both sides by 10.

s = 16/10 = 8/5 = 1.6 mph
