Answer:
x^4-3x^3+2x^2+2x-2
Step-by-step explanation:
Multiply the second the second parentheses by each term from the first parentheses
Distribute x^3 through the parentheses
Then collect all like terms to get an answer of x^4-3x^3+2x^2+2x-2
Answer:
option one is the correct answer
I think you are right so far what i've done comes out to your answer.
Answer:
The answer to your question is
x = -2 and y = 10 or x = 10 and y = -2
Step-by-step explanation:
x + y = 8 (1) from (1) x = 8 - y
xy = - 20 (2)
Solve them by substitution
(8 - y) y = - 20
8y - y² = -20
y² - 8y - 20 = 0
( y - 10) (y + 2) = 0
y - 10 = 0 and y + 2 = 0
<u> y1 = 10 </u> <u>y2 = -2</u>
x1 = 8 - 10 x2 = 8 - -2
<u>x1 = -2</u> <u> x2 = 10</u>
