Answer:
(x - 1)( x - 2) (x + 2) = x³ -x² -4x + 4.
Explanation:
1) Given equation:
3 5x x + 2
- ------- + -------- = ---------------
x + 2 x - 1 x² - 3x + 2
2) So, the denominators are x + 2, x - 1, and x² - 3x + 2
3) The LCD is the product of the common and non common factors raised to the greatest power.
4) x + 2, and x - 1 are already prime factors
5) Factor x² - 3x + 2
x² - 3x + 2 = (x - 2)(x - 1)
6) Then, the factors are x + 2, x - 1, and x - 2, and the LCD is the product of them:
(x - 1)( x - 2) (x + 2)
7) If you expand the products (distributive property) you get:
x³ -x² -4x + 4.
Here you go sorry if pix came out upside down
Part 1:
180 = 5p+98 + 9p-2
180 = 14p + 96
84 = 14p
6 = p
part 2:
angle S will be the same as angle Q, so:
9p-2
9(6)-2
54-2
M
Answer:
6x^2 + -10
Step-by-step explanation:
Hi there! I'm glad I was able to help you answer this polynomial expression!
All we're really doing to solve is combine like terms.
(5x^2+2) - (-4x^2+7) + (-3x^2-5) = _____________
5x^2 + 2 + 4x^2 + -7 + -3x^2 + -5
(5x^2 + 4x^2 + -3x^2) + (2 + -7 + -5)
6x^2 + -10
The terms that have x^2 at the end are in bold letters so you know what we're combining them - the other numbers are the separate like terms.
Simplified, our answer is 6x^2 + -10.
